Excuse me, can the master leave the primer of the car paint?

You can't. When painting, the master will spray a layer of primer without leaving it. Primer is the first basic paint in the process of automobile spraying. Its main function is to improve the adhesion of topcoat, and at the same time, it plays an anti-corrosion and anti-rust role on metal surface. Whether it is a new car or an old car, normal primer spraying needs to be carried out twice. The new car is electrophoretic and intermediate coating, and the old car repair is called the first primer and the second primer.
