How to Remove Car Paint?

If only a small amount of paint is scratched, there is no need to go to a 4S store for partial repainting. You can visit a car beauty shop and have the staff use a polishing machine with fine wax to restore it to its original condition. The introduction to car paint is as follows: 1. Composition: Automotive topcoat is generally composed of three parts: electrocoat, primer, and color paint. The topcoat is the outermost layer of automotive coating. In terms of appearance types, it is mainly divided into what people commonly refer to as metallic topcoats and non-metallic topcoats (also known as solid colors). The difference between the two is essentially just the clear coat and solid color paint, because the outermost layer of metallic paint topcoats must be coated with transparent clear paint, while in essence, clear paint is just solid color paint without pigment. 2. Structure: On top of the car body steel plate, there are four paint layers: the electrocoat layer, the intermediate coat layer, the color paint layer, and the clear coat layer. These four layers together form the car paint layer, commonly referred to as the original factory paint. The car paint repaired by a 4S store (or non-4S store) after scratches is only equivalent to part of the intermediate coat layer + color paint layer + clear coat layer.
For car paint decontamination, I often use simple household methods. For stains like tree sap or bird droppings, never scrape them off forcefully. The safest way is to use neutral car shampoo with clay bar to gently rub them off, which can be bought at supermarkets. For tar stains, use a dedicated tar remover—spray it on, wait for three minutes, then wipe with a soft cloth. For stubborn marks, I've tried applying mentholated oil, but remember to always wax the paint afterward for protection. Last year, a friend had paint splashed on their car roof and used gasoline to clean it, which ended up corroding the original paint, costing a fortune to repaint. When handling it yourself, always test in a small area first—original paint is much more delicate than repainted surfaces.
