How to paint the bumper?

Bumper painting method: 1. First of all, we need to prepare some things, such as silica sol, silica gel solvent sandpaper, and most importantly, paint and softener. 2. Then we prepare a baffle to cover the part near the bumper to prevent us from spraying it later. Then we use silicon solvent to clean the parts that need painting. 3. Then we can use protective silica sol to coat a protective film on the whole surface of the car to repair the scratches on the bumper; 4. Next, we carefully polish the whole surface of our bumper with sandpaper dipped in water, and then we spray the surface with spray paint; 5. Finally, we will finish painting bumper top coat and add softener. If you use metallic paint, you can wait for five minutes to dry before spraying the bright layer.
