Can small scratches on a car be removed by polishing?

[SanGage]

Small scratches on a car can be removed through polishing. Polishing utilizes the high-speed rotation of a polishing wheel to grind away the oxidized layer and dirt on the car paint surface, effectively eliminating minor scratches. Here are some relevant details: 1. A car's paint surface consists of four layers, from the inside out: the electrophoretic layer, the primer layer, the base coat (color layer), and the clear coat. After the car body is assembled, the entire body is immersed in an electrophoretic bath to form an electrophoretic layer, which prevents rust. After the electrophoretic process, a primer layer is applied to the body; this layer also prevents rust and enhances adhesion to the next paint layer. Then, the base coat (color layer) is sprayed on, which is the visible colored layer that gives the car its aesthetic appeal. Finally, the clear coat is applied—a transparent paint layer that protects the base coat and enhances the paint's glossiness. 2. It's important to note the frequency of polishing. Frequent polishing can damage the car paint to some extent, as the paint becomes thinner with each polishing session, leading to a decline in the body's self-maintenance capability.
