What are the layers of car paint?

[StSadie]

Car paint consists of four layers from the inside out: the electrocoat layer, the primer layer, the basecoat layer, and the clearcoat layer. The electrocoat layer primarily serves two functions: rust prevention and enhancing the adhesion of the paint layers. The primer layer is the intermediate layer between the electrocoat and the basecoat, providing UV resistance, protecting the electrocoat, improving rust prevention, and ensuring the smoothness and impact resistance of the paint surface. As the name suggests, the basecoat layer is the colored layer, offering direct visual color perception—whether red, black, kingfisher blue, or Pittsburgh gray. The quality of the basecoat application directly determines the expressiveness of the car's color, making it functionally crucial. The clearcoat layer is the outermost layer of the car paint, a transparent layer that can be directly touched with fingertips. Its main functions are to enhance the paint's gloss, improve texture, provide UV protection, and prevent minor scratches.
