Is it serious if the car is scratched and the white paint is exposed?

[QuinnFitz]

When the car is scratched and the white paint is exposed, it needs to be dealt with promptly. Here is some relevant information about car paint: Composition of car paint: The body paint of a car consists of four layers, from the inside to the outside, which are the electrophoretic layer, the intermediate coat, the color coat, and the clear coat. The key function of the electrophoretic layer is rust prevention. After the entire body is assembled, it is immersed in an electrophoretic tank, forming an electrophoretic layer on the surface of the body. Intermediate coat: Above the electrophoretic layer is the intermediate coat, whose main functions are rust prevention and improving adhesion to the next layer of body paint. Above the intermediate coat is the color coat, which primarily serves an aesthetic purpose. The various colors of the car body that we usually see are mostly presented by the color coat. Clear coat: The outermost layer of paint is the clear coat, which is a transparent layer. The clear coat enhances the glossiness of the body paint and protects the color coat. Most minor scratches usually remain on the clear coat, but these scratches can be removed through simple polishing.
