Does Replacing the Trunk Lid with an OEM Part Require Painting?
1 Answers
Replacing the trunk lid with an OEM part requires painting because the original OEM trunk lid does not come with a painted surface. Therefore, it needs to be painted at the 4S shop before installation. Below is the relevant information: 1. The car's body paint is complex, consisting of four layers. From the inside out, they are the electrophoretic layer, the primer layer, the base coat layer, and the clear coat layer. 2. Each layer of paint has a unique application process and function. Details are as follows: (1) After the entire body is assembled, robots immerse the body in an electrophoretic tank, forming an electrophoretic layer on the entire body. The main function of the electrophoretic layer is rust prevention. (2) After the electrophoretic layer is formed on the body surface, robots apply the primer layer, which also serves to prevent rust and enhances adhesion to the next layer of body paint. (3) Above the primer layer is the base coat layer, whose main function is aesthetics. The various body colors we see are presented by the base coat layer. (4) The outermost layer is the clear coat layer, which protects the base coat layer and enhances its gloss. The clear coat layer is the most vulnerable paint layer, and most minor scratches typically remain on this layer.
