Car door rust repair method is: first spray with rust remover, then sand and repaint. There are many reasons for car door rust, which may be caused by substandard steel plate quality, blocked drainage holes, or damaged paint that was not repaired in time. The car's paint consists of four layers, from the inside out: the electrophoretic layer, the intermediate coat, the color coat, and the clear coat. After the entire body is assembled, robots immerse the body in an electrophoretic tank, forming an electrophoretic layer on the surface, which serves to prevent rust.
