Before beginning any block sanding technique, ensure the car’s surface is thoroughly cleaned and dried to prevent contamination from debris or moisture that could affect adhesion. A proper base coat application is also crucial; it acts as a shield between the paint and sandpaper, protecting both and ensuring a smoother finish. Remember, successful block sanding involves patience, precision, and paying attention to detail—a process that prioritizes quality over speed in car collision repair and auto body shop settings.
