Do-it-yourself car painting - how to remove old paint

Removal methods

Let us consider in detail the existing methods of removing paint and answer the question that concerns you, how to wash off or remove paint from a car.

Chemical method

The essence of the method is based on the ability of chemical solvents to soften paint. After applying chemicals to the surface of the car body, solvent reagents destroy the enamel resin. Therefore, it can be easily removed using a spatula or scraper. Car dealerships sell a special solution for removing old paint from a car. It can be of two types:

Important! Chemicals can damage the plastic parts of your car.

The process of chemically removing paint must be carried out in the following sequence:

Did you know? Bright car paints are called “candy paints”. This name comes from the American word “candy” - lollipop.

Mechanical method

The mechanical method is more accessible, but also more labor-intensive. It is often used for localized paint removal. The process of removing paint mechanically must be carried out in the following sequence:

Thermal

The essence of this method is to soften the paint when heated and remove it with a scraper. You can heat it with a hair dryer, gas torch or blowtorch. This method is used to remove paint from individual dismantled parts. All plastic and rubber elements must be removed as they will be subject to deformation.

Important! Remember safety precautions: when heated, old paint releases toxic substances.

The thermal paint removal process is carried out in the following sequence:

Folk remedies

If you have a question about how to remove and how to remove paint from a car with your own hands, then sometimes you can remove it with improvised means.

To remove paint, use a 30% caustic soda solution. It is applied to the surface of the car with a brush and left for 12 hours, and then washed off with hot water. However, this will take a long time and require a large amount of soda, since the solution will constantly drain from vertical surfaces.

Some craftsmen prepare a paste that can be used to remove paint. Here are a few recipes for this pasta:

Current methods

Since there are a number of options for removing paint from a car, it is better to find out about them in advance, as well as possible side effects from using a particular product.

In fact, removing paint from the body of your car is not difficult. But the main problem lies in the fact that under the non-original paint there is an original paint layer. Therefore, you need to carefully choose what is better and safer to remove only the excess without affecting the base paintwork.

The presented options for dealing with paint can be divided into 2 large categories:

Each category should be discussed separately and the most effective options presented.

Folk remedies

If you are thinking about how and how to safely remove foreign paint from a car without damaging the original paint and varnish materials, you can use solutions that have come from the people.

Here it is important to understand that the time the foreign dye remains on the surface of the body, rubber or plastic elements of the car plays a decisive role. Removing paint from plastic that has appeared on a car for some reason is somewhat easier, since, if necessary, plastic elements are easier and cheaper to replace.

We offer several popular solutions for scrubbing and removing dirt in the form of foreign paint from a car.

All presented methods are quite effective. But they are also accompanied by a certain level of danger to the original paint layer.

Be extremely careful and careful. If in doubt, it is better not to touch any extraneous traces of paint and take the car to a specialized service center.

Modern means

Also in automotive supply stores you can find an extensive list of tools that can be used to solve the problem.

These are professional liquids and more, allowing you to cope with all kinds of contaminants, including paint.

It is believed that it is always better to use specialized tools. And since it concerns foreign paint on the car, then supposedly you should only use solutions from car dealerships.

In practice, this is not an entirely true statement. Much depends on the nature of the contamination, its size and strength. Sometimes you can get by with improvised means and ordinary soap solution. In other situations, aggressive chemistry will be needed, since weaker substances will not cope with the task.

Safety regulations

Using a thermal method of removing paint, you expose yourself to the risk of getting a thermal burn, since some parts of the hair dryer are heated to high temperatures.
With the chemical method, the inhaled air contains toxic substances, and with the mechanical method, the air is highly dusty. Therefore, it is imperative to use protective equipment for the skin, respiratory system and eyes, using thermal gloves, tight overalls, high-quality respirators, and goggles. It is also necessary to carry out this work in well-ventilated areas or in the open air. Take your safety responsibly, and this will protect your body from negative consequences.

But both with complete and local paintwork repairs, you will in any case need to clean the car of paint, and if you plan to do everything yourself, then without knowledge of all technologies it may take you a lot of time and effort at this stage of work. We will try to offer you some of the most effective solutions to this issue.

What is needed to carry out the work?

Tools and consumables will largely depend on the method you choose for removing the coating from the car body, as well as on the type of part that you plan to restore, whether it be wheels or a car bumper. But there is a basic set that you will need.

General recommendations

Every car owner understands perfectly well that when removing paint from cars, one should be extremely careful and attentive. Otherwise, the likelihood of permanently damaging the paint layer or plastic element of the machine increases.

Be prepared for painstaking and thorough work. By using aggressive substances or improperly distributing your forces, you can easily remove not only traces of other paint, but also destroy the car’s paintwork. Then you will have to repaint a section of the body, which results in a fairly decent amount of money.

There are several general rules that are strongly recommended to be followed. This will avoid unpleasant consequences when trying to get rid of contaminants on your own.

Based on the above recommendations, every motorist will be able to correctly approach the problem of the appearance of foreign paint on his car.

How to easily remove paint from metal: 3 approaches

Removing paint from a car is a complex process, since most manufacturers use special compounds that are resistant to external influences. All methods used can be divided into accessible ones, the profitability of which is minimal, and professional ones. In the case of the latter, the use of expensive, highly specialized tools will be required. To carry out the work, you should have kerosene, a spatula, a grinder and a heat gun on hand.

There are three technologies for removing old paint:

The chemical method is considered the simplest. Today there are a large number of sprayers on sale designed specifically for these purposes. To get results, you only need to apply the product to the surface and wait a while for the reaction to occur. The downside of the approach is toxicity. The thermal method involves heating old paint, quickly softening it and then removing it with a spatula.

Important! The thermal method cannot be used when interacting with a cast iron or galvanized surface.

The mechanical method is manual stripping using a metal brush or sandpaper. It is only suitable for processing small surfaces, because it involves long-term work with the application of force.

Completing of the work

The procedure for performing work using a special composition for removing old paint:

  1. Carefully read the instructions for using the remover.
  2. Prepare your workplace, materials and tools (paint remover itself, brush, spatula, rags, running water, safety glasses and gloves, respirator).
  3. Position the bumper comfortably to get the job done. Consider how you will change its position in order to apply the composition to all the required places. Wear protective equipment.
  4. Apply the aerosol or gel using a brush to the painted surface of the bumper, being careful. Make sure that the composition evenly covers absolutely the entire previously painted area.
  5. To obtain the desired result, allow the time specified in the instructions for the chemical reaction between the applied composition and the painted surface to complete. Is it possible to paint a car without a primer over old paint? A visual indication that the process is underway will be the formation of swellings and detachments on the treated area.

Temperature effects for paint removal: specifics

This principle is based on the technology of preliminary softening of the old coating by heating it. To do this, an industrial hair dryer, gas burner or compact blowtorch is most often used. Once the paint has softened, it can be quickly scraped off with a regular metal spatula. Exposure to temperature is an easy-to-implement and effective way to remove paintwork from a body. But it also has its drawbacks.

It should not be used if paint is being removed from plastic, since the material itself will begin to melt when the temperature reaches 200°C. It is also necessary to strictly observe safety precautions when working with equipment that creates a directed stream of open flame. When carrying out work in closed workshops, the use of such devices is excluded, since when heated, the paint releases toxic substances, which, in the absence of ventilation, will poison the body of the master.

Methods for removing paintwork using specially designed means

The most common means used by car owners to remove paint are:

Cleaning with clay
Scratch paste. To remove dyes, use a paste that can be found at any auto store. Apply it to a hard cloth with micropores, which is sold in the same section of the store. Using scratch paste

After removing paint from the body or windows of your vehicle, be sure to apply wax to it. It will prevent dyes from sticking to the body.

Removing layers of paint from a car body - cheap methods

You can prepare a completely effective and high-quality paint remover with your own hands. For this you will need good caustic soda and some water. A solution containing 15-20 percent of this material can remove the paint layer by layer. But to work with such a liquid, personal safety must be observed. Soda can quickly corrode not only enamel, but also skin. Also, when looking for an idea on how to remove paint, you can use the washing method:

No chemicals are used. The only liquid involved is water, but in this case there will be a lot of manual work. This kind of washing of even one small part can take a lot of time, but the layers will be removed exactly to the extent that you need. After washing down to the primer, you will need to lubricate the metal parts with a degreasing solvent, and you can paint.

Special paint removers – Abro or Body 700?

At your auto store, you can find liquids specifically designed to remove layers of paint from your car. Washing helps to clean the surface down to metal or remove the required number of layers of paint material. The Body company offers a fairly effective option - Body 700 liquid. Removing paint from a car will happen in a matter of minutes, and you won’t have to work for it. But we also suggest looking at Abro products with the following features:

This wash works great, even if you need to remove the factory paint layers. The product meets high quality standards. If you are going to purchase such a specialized material, then Abro paint remover is the recommended option. Many specialists in the painting business use just such products to perform the necessary tasks. But make sure that you buy the original product, there are many fake liquids with low quality.

Metal on disks - we wash the paint professionally

Wheels often need to be updated when changing or freshening up the appearance of your car. This is what wears out quite quickly, so you constantly need to take care of this element of the car. In this case, washing off the old paint is necessary, since otherwise it will not be possible to carry out the normal application of new decorative materials. You need to wash it off with special means, since rinsing and caustic soda will not help here.

The problem is that the surface of the disk has many curves and small details that are extremely difficult to process in the required mode. For this reason, you need to perform high-quality treatment with a special liquid. You can use the products presented above or choose other brands. It is only important to read the instructions and understand that this particular option is suitable for your task of processing car wheels.

How and with what to remove paint from a bumper

Sooner or later, car enthusiasts need to repaint their car bumper. This can be caused by many reasons:

  1. Local damage due to contact with various objects during parking.
  2. Natural wear and tear of the factory coating.
  3. Damage from flying stones and other objects hitting the bumper while driving.
  4. Cases of vandalism by unauthorized persons (scratches or other accidental paint).

All this forces us to take measures to repaint the bumpers.


Bumper with damaged paintwork

What are the possible solutions?

If you decide to repaint them yourself, the question immediately arises: how to remove the old paint? In practice, several main options for solving this problem are used:

  • thermomechanical method - its essence is that the old paint applied to the bumper is heated to a temperature at which it begins to peel off. Then it is removed with a regular spatula. Hair dryers of different power are used for heating. The use of open flame (for example, from a blowtorch) is not recommended. This is dangerous from a fire safety point of view. In addition, you may not keep track of the degree of heating of the bumper material (especially if it is non-metallic) and melt it. The work should be done in small sections. This method, like the previous one, is low-productivity and labor-intensive.
  • using washes - it should be noted that the wash can be performed both using modern special compounds and traditional methods.

Modern compositions have properties that allow you to remove paint from a bumper quickly, effectively and with minimal labor costs.

They are available in the form of aerosols or gels. The coating is washed off quickly (within a few minutes) in two stages: applying the product to a previously painted surface and removing the old coating.

Characteristics of compositions for removing old paint

Today, compositions for washing are both domestic and imported. They have the following main characteristics:

  • non-toxic;
  • non-flammable;
  • have a high safety class;
  • have high performance; previously applied paint loses its properties within a few minutes;
  • do not react with plastic.

How to choose the right composition

The selection of compositions for removing paint is made depending on the material from which the bumpers are made (plastic or metal). Plastic bumpers must be marked with the composition from which it is made.

Depending on this, the composition for processing old paint is selected. Chemical compounds of removers containing benzene, toluene, and xylene cannot be used for plastic bumpers. Their impact will cause destruction of the plastic composition.

Completing of the work

The procedure for performing work using a special composition for removing old paint:

  1. Carefully read the instructions for using the remover.
  2. Prepare your workplace, materials and tools (paint remover itself, brush, spatula, rags, running water, safety glasses and gloves, respirator).
  3. Position the bumper comfortably to get the job done. Consider how you will change its position in order to apply the composition to all the required places. Wear protective equipment.
  4. Apply the aerosol or gel using a brush to the painted surface of the bumper, being careful. Make sure that the composition evenly covers absolutely the entire previously painted area.
  5. To obtain the desired result, allow the time specified in the instructions for the chemical reaction between the applied composition and the painted surface to complete. A visual indication that the process is underway will be the formation of swellings and detachments on the treated area.
  6. Using a spatula, remove the resulting mass from the treated area.
  7. Rinse the bumper under running water and carefully evaluate the result of the wash. If you have previously puttyed the bumper, pay attention to whether it was fully exposed to the composition. The effect should be the same as for the previously applied paint layer. If the old paint and putty is not completely removed, you need to repeat the process.
  8. When even after this there is no result, and the old paint remains in some hard-to-reach places, you can clean them with any thin abrasive tool.
  9. If it is unacceptable for you to use an abrasive tool for this purpose, apply a spot remover to these areas. After this, perform all the necessary operations again. The result must be achieved.
  10. Treat the paint-free surface with white spirit.

Folk practice of resolving the issue

A few words about what a “folk” wash is. These are all kinds of chemicals that are not intended for this purpose in their intended purpose. However, using them, the goal is still achieved - the paint is washed off. An example is a drug such as dimexide. It is sold at any pharmacy. After moistening a rag with it and securing it to the bumper, after half an hour, expect the result - the coating should come off. There are other folk methods for solving the issue, but there is no need to dwell on them.

It should be said that all folk methods must be treated with caution. They are not always correct or effective. Sometimes they can be downright dangerous. Therefore, it is better to use tested and specially designed drugs for this purpose.

8 Easy Ways to Remove Dents on Your Own Without Ruining the Paint “Car Service and Repair :: WonderHowTo

There are only three things certain in life: death, taxes, and a dent in your car or truck. Even if you're as careful as you can be, you can't always chalk up runaway shopping carts, errantly thrown soccer balls, light posts out of nowhere, and other real-life annoyances.

Even though you have a dent or ding, the next thing on your mind is undoubtedly how to get it out. Of course, you can take it to a body shop or friendly neighbors, but their prices can be incredible. especially if they want to remove the paint or use body filler first. $200 for this tiny dent?! I don't think so.

Instead, save some of that hard-earned money and do it yourself. There are many ways to get a small dent or paint on your car without ruining the paint, and you don't have to be a mechanic to do it.

However, not all of these techniques will work for your specific vehicle; Your mileage may vary depending on where the dent is located and what your dash, hood or bumper is made of (aluminum, carbon fiber, plastic, fiberglass, steel, etc.). For example, aluminum has slight memory properties, so removing dents without painting is much more difficult.

Method 1: Using a plunger

Not only can you unclog your drain with a plunger, but you can also get small to medium sized dents out of your car. Just spray some water on the plunger and dent and start pushing and pulling until it pops out. Be sure to use a cup plunger (for sinks) rather than a flange plunger (for toilets).

Method 2: Using Boiling Water

Handling an object is one of the easiest ways to get a dent. So for plastic bumpers, even if you try to remove the bumper, it will still be difficult to push the dent out due to how malleable the plastic is. Solve this problem by boiling some water in a pan and throwing it on the dent.

Once you have filled the water, reach behind the bumper and try to put the dent back in. The high temperature of the water should make the plastic a little more flexible, making it easier to snap into place. ,

Since the heat won't last very long, you'll have to work quickly. If the dent doesn't go away completely, continue pouring boiling water over it until you can pull it back out.

Method 3: Using a hair dryer and compressed air

Another popular method for removing plastic car dents involves using two popular household products: a hair dryer and compressed air.

Start by heating the car dent with a hairdryer to its highest temperature, which will expand the plastic of the car. Once it gets hot enough, take a can of compressed air, turn it over and start spraying the same area. Since the cold air will cause the plastic to shrink, the dent will pop out.

(1) A heat gun, hair dye or lighter will do. (2) Then just use canned air. images from Yagelski / YouTube

Method 4: Using Dry Ice

Primarily used as a cooling agent, dry ice can be used to remove small dents from your vehicle. While you're wearing protective gloves, hold a piece of dry ice on the dent and rub it until you hear your dent click into place.

Apply dry ice as many times as you need, but it should eventually appear unless the dent is too deep. You can also try heating the dent first with something like a hair dryer (similar to the hair dryer and compressed air tip above), and then apply dry ice to it.

Method 5: Use a vacuum cleaner and potty

Suction is one way to remove a dent, but the problem is finding a dent puller with the right power. Well, why not just create your own? All you need is a pot (or bucket), a vacuum cleaner, and some tape, and you'll be able to get that dent out of your car in no time.

Simply make a small hole under the pot, secure the pot around the dent, place the vacuum hose over the hole under the pot, and turn on the vacuum. If the dent is not too shallow, the suction created should push your dent out.

Method 6: Use hot glue, wood dowels and screws

When you try to remove dents yourself, you always run the risk of causing further damage to your car if you worsen the dent or scratch the paint. A safe way to make large dents on your car is to use some wooden dowels, some screws and a hot glue gun.

Simply place two nails on each side of the dowel and apply hot glue to the bottom. Place the dowels, adhesive side down, in the area around the dent, repeat as many times as needed to cover the area, let them dry, and pull each one out until the dent is gone.

Place and pull the same dowels in several different places along the dent until most of it comes out. If you are going to try this method, make sure you have enough glue and patience. Use alcohol or heat to release the adhesive from the car.

Method 7: Using a Long Metal Rod and Knockdown

When a car is dented, not only does the metal go inward, the surrounding edges of the dent also rise up, creating something like a small volcano. This means that popping the dent out is not the way to go.

George Gokaj, a Paint Dent Repair (PDR) technician, repairs dents by working on both sides of the dent. Using a combination of a long metal rod underneath and a knocking or knocking tool (wood or rubber) on the top side, he can pull the dent completely out of the car. And boy, does it work.

Method 8: Use a special tool

If you have no success with any of the above methods, you can also try Pops-a-Dent or a suction cup dent remover.

Which method worked best for you?

If you want to try something and don't have a ton of tools at home, pick up a dent removal kit that contains tools specifically made to remove dents using many of the methods described above.

Have you tried any of these methods, or did you end up biting the bullet and hiring an auto repair shop to do the job for you? If you've used another DIY method to remove dings and dings from your car, be sure to let us know below!

Even if you are lucky enough not to be injured in a car accident, it is rare to escape without some kind of damage to your vehicle. It goes without saying that there are some things you shouldn't try to fix yourself, but if it's just a scratch or dent, DIY might be a cheaper option.

You can remove the smallest dents from your car with a hair dryer and compressed air , dry ice , or even hot glue and corks , but if it ends up isolated on your bumper, all you need is some boiling water.

Yes, a little hot water is all you need

The heat allows the plastic to expand and become flexible so you can push it back into place.

Then run cold water over the area to shrink the plastic into place. Check out redditor SX_PNTHR's Imgur album for a photo walkthrough and read the comments for more tips and tricks.

Results vary on older cars

However, this method is not for everyone. A commenter indicated that this method is not suitable for most older vehicles. New urethane body parts can handle this, but there is a good chance of ruining the paint on the old metal parts.

And you may have to remove the bumper.

It's also probably more trouble than it's worth if the dent is in a location where you'll have to remove the bumper to get to it. But, if you want to do this, watch the video below to see how to remove the wheel and bumper for the hot water method.

Removing paint mechanically

The mechanical method is the best option for processing a small area of ​​the car surface, because it requires a lot of time. In this case, you will need the following:

A sanding machine will allow you to thoroughly remove paint from the entire car, and use a wire brush as a sanding disc.

It is practiced to use a compressor equipped with a sandblasting nozzle. But to remove old paint from a car using this method, experience is required; without professional training, it is quite problematic to remove the previous layer of paint.

You should refrain from using this method if the paint is elastic, because it will not be possible to properly clean the surface of the car. And the purchase of special equipment will significantly affect the budget.

Mechanical removal of paintwork from a car does not require special preparation; it is enough to gently press the grinding machine disk onto the area being treated (avoid excessive force); periodically remove loose particles. After completing the “cleaning”, wash off the dust and dirt with water.

Removing paint mechanically

Basic methods for removing paint

Three main ways to get rid of old paint are widely known:

Most often, motorists, despite the high cost of work, choose the mechanical method. The technology for this method of metal cleaning is quite simple; this method is effective, but requires a lot of labor. The car is treated with a metal brush or sandpaper, or a drill or angle grinder can be used. The painted surface of the car is cleaned to a shine, and then washed and degreased before painting. Sometimes sandblasting is used, but when using it, you must remember to additionally sand the surface of the car, since grains of sand may remain in the upper layers of the metal.

The thermal method of removing paint from metal is that the paint-coated surface of the machine is heated using an industrial hair dryer, a blowtorch or a gas torch. After the paint has softened, it is cleaned off with special scrapers, brushes or other tools. This is a fairly simple and effective way to remove paint, but it is not very practical when you need to treat the surface of the entire car. It is best suited for cleaning individual parts.

Removing paint materials from plastic surfaces

Among automotive plastic parts in the painting process, it is worth highlighting two options. These are interior parts and parts of the exterior of the car. The bumper most often has the same coating as the metal parts of the car. The inner plastic is painted in a different type of painting material. The question arises as to how to remove paint on a plastic part. There are several options for action in this case:

This procedure is more subtle than removing paint from metal, so it must be done carefully. If the surface of the plastic is damaged, the part will have to be leveled, which will bring completely different costs and time. If you need to completely remove the paint layer from a product, it is better to do it yourself. Even when ordering professional painting of an element in a chamber, you will receive significant savings on the preparatory processes.

How to remove paint from a car without damaging the paintwork - tips from experienced people.

Before wiping anything off, I advise you to try the solvent on the inside of the body, for example, on the rear side of the door from below, where few people will notice if the solvent corrodes the paint. We literally apply a drop of solvent to the body and wait about 5 minutes. The internal surfaces of the body, as a rule, are simply painted, not covered with a thick layer of varnish like the outer side of the body. And if the solvent does not remove the paint, then you can safely scrub the paint off the car body with it. If you still have a strong solvent, you will have to combine it with pouring water on the part that you are wiping immediately, otherwise the solvent will leave marks on the body, although in any case it is worth rinsing the surface with water after wiping. In one place the paint did not come off well, since the body was gray and the paint was red. I had to polish it, I used an abrasive polish and a regular one. After polishing there was no trace of paint left.

Let's sum it up

There are various products that are used to remove paintwork. Removing old paint from metal or plastic can be done using different tools and technologies. Using simple options for inexpensive materials, you will have to work hard and do a lot of work with your own hands. However, the procedure will be cheap. You can give preference to products that work perfectly and do not present any problems. But such liquids cost a lot and will require compliance with a number of instructions.

When working with any chemically active elements, do not forget to protect yourself. If you do not want to do the work yourself, you can order services from specialists. But in this case, you will have to pay quite a lot for materials, work itself, as well as the company’s standard markup. You can easily perform these tasks with your own hands, even without special training.

Of course, if the old layer of paint holds well, then you can leave it, only matte the surface and apply a primer. But both with complete and local paintwork repairs, you will in any case need to clean the car of paint, and if you plan to do everything yourself, then without knowledge of all technologies it may take you a lot of time and effort at this stage of work. We will try to offer you some of the most effective solutions to this issue.

What is needed to carry out the work?

Tools and consumables will largely depend on the method you choose for removing the coating from the car body, as well as on the type of part that you plan to restore, whether it be wheels or a car bumper. But there is a basic set that you will need.

You will also need detergents to pre-clean the surface from dirt and dust.

Basic ways to remove paint from a car

Based on their technology, there are three main approaches on the market: chemical, mechanical and thermal. Each method has both pros and cons.

In order to use the chemical method, you will need to buy paint remover and a brush to apply it to the surface of the car body. You will also need a spatula.

When machining, a grinding machine and abrasives of various sizes are used, sometimes sandpaper with a block to remove the coating in hard-to-reach places.

For heat treatment, you will need a good industrial hair dryer or blowtorch complete with a scraper and a stiff metal brush.

Chemical method

This is one of the effective options for removing paint from a car. Its essence is simple, you apply the material to the surface with a brush, wait 10 - 20 minutes and then use a scraper to remove the old layer of paint. After you apply the chemical composition to the problem area of ​​the body, its reagents will begin to destroy the enamel resin and it will begin to move away from the metal surface.

There are two types of such paint remover:

There are also cases when formic or phosphoric acid is used to clean paint from a car. Chemical compounds are often used to remove paint in hard-to-reach places where it is impossible to reach with a grinding machine.

Remember about personal protection when working with chemicals; do not allow this material to come into contact with the skin or other parts of the body. To do this, use goggles, gloves, a protective suit and a respirator.

If you locally need to remove a small area of ​​paint, then for these purposes you can use white spirit, solvent No. 648 or R-4.

Work technology:

At this point all work is completed.

Mechanical method

This is a more labor-intensive option for removing acrylic paint from a car. To implement it, use a grinding machine and, in rare cases, for local repairs, sand the surface manually using sandpaper.

If the car is insured, then with its full insurance there should be a section on vandalism, which should be included in the list of risks. Therefore, before you try to remove the paint yourself, you must first contact an insurance agent who can advise you and, if the answer is positive, can direct you to the right workshop, where all costs will be covered by the insurance company. And when asked how to remove someone else’s paint from a car or how to remove paint splatters from a car, professionals will take care of it.
