If the amount is not enough, you can mix the original paint with black or white paint to make a primer. When it's cold, wait for the paint to dry before spraying the second paint.

The correct painting techniques for car painting include gun adjustment, gun holding, gun walking, etc. The following are the specific contents: adjustment gun: Before spraying construction, the spray gun and related equipment should be cleaned and in normal working condition to check whether the spray gun produces the ideal spray shape.

What is the function of car spray varnish?

1. The first is electrophoretic paint, whose main function is to prevent rust. The second is medium coating, whose main function is to resist ultraviolet rays, resist stone strikes, and lay the foundation for color paint. The third is the color paint layer, the main function of which is beauty. The fourth is the varnish layer, whose main function is to make the car body shiny and resist stone attacks.

The orange peel phenomenon of paint is actually caused by the dry spray phenomenon of paint, the main reason is the high viscosity of the paint.A special diluent can be added appropriately; in addition, the pressure of the spray gun should be appropriately reduced; the distance between the nozzle and the sprayed surface is about 30cm, and it should be sprayed vertically.

To avoid orange peel, you should understand how orange peel is produced. The production of orange peel is related to the viscosity of the paint. If the viscosity is high, it is not easy to level the orange peel. If the viscosity is reduced appropriately, the orange peel will disappear.
