Car paint is usually baking paint. After the welding of the car frame and body is completed inside the car manufacturing factory, the next step is painting, generally speaking, the first step is primer. Dip the eggshell into a syrup shaped bathtub and remove the baking primer.

Then it is sent to the cleaning workshop and sprayed with paint using the electrostatic spray painting process. Then dry at around two hundred degrees. To complete more refined processing, you need to apply a layer of varnish. In this way, the process of painting is over.

Its process is not as messy as you imagine, and the following are the relevant processes:
