Painting The painting process begins after all the needed preparations have been completed. Barstow Auto Body team in Barstow uses the spray gun to apply three to four layers of paint. With the side-to-side sweeping motion, we ensure that each coat is thin and is applied evenly to create a design that truly stands out. The drying time usually depends on the type of paint used and ranges from 20 minutes to one hour. To avoid any residue, before the last coat is applied, Barstow Auto Body Barstow branch team sands and wipes the surface once again. Using the same technique, the lacquer thinner is then sprayed. After the masking tape is removed, the last step in the process is buffing of the painted surfaces.
