Solutions for a small chipped paint on the car door: If the area is very small, you can use a touch-up pen to handle it yourself, which can be purchased at large supermarkets. If the area is relatively large, you need to go to a 4S shop for professional technicians to repair the paint. The car paint consists of four layers, from the inside to the outside: the electrophoretic layer, the intermediate coat, the color coat, and the clear coat. 1. Electrophoretic layer: After the body is assembled, the entire body is immersed in an electrophoretic pool, forming an electrophoretic layer on the surface of the body. The function of the electrophoretic layer is to prevent rust. 2. Intermediate coat: After the electrophoretic layer is formed on the body surface, robots will spray an intermediate coat on the body surface. The function of this layer of paint is also to prevent rust and improve the bonding ability with the next layer of paint. 3. Color coat: This layer of paint is the various body colors you usually see, and it serves an aesthetic purpose. 4. Clear coat: This layer of paint is the outermost layer, and its function is to protect the color coat and enhance the glossiness of the paint.
