What can be used to deal with scratched car paint?

[JasonLee]

There are several methods to deal with scratched car paint: 1. If the scratch results in paint loss, you can first use a touch-up pen to repair the paint, which can prevent the metal body panels from rusting. After a simple touch-up, it is recommended to go to a professional paint repair shop or a 4S store for further paint restoration. 2. If the scratch does not damage the primer, no treatment is needed because without primer damage, the metal cannot come into contact with air and moisture, thus preventing rust on the metal body panels. Below is some relevant information: 1. A car's paint surface consists of four layers, from the inside out: the electrocoat layer, the primer layer, the basecoat layer, and the clearcoat layer. After the entire body is assembled, it is immersed in an electrocoating bath, forming an electrocoat layer on the surface. 2. The main function of the electrocoat layer is rust prevention. After the electrocoat layer is formed, robots spray the primer layer, whose main function is also rust prevention. This layer is commonly referred to as the primer. The primer layer also enhances adhesion to the next paint layer. Above the primer layer is the basecoat layer, whose main function is aesthetics. The various car colors we see are produced by the basecoat layer. The outermost layer is the clearcoat layer, a transparent paint that protects the basecoat layer and enhances the gloss of the car's paint surface. Most fine scratches also remain on the clearcoat layer.
