Standard Operating Procedure for a two sided bumper cover repair. A two sided repair includes damage that goes through the substrate, as in a deep scratch, crack, or tear. This method is done with a reinforced scrim backing repair and a dished-out cosmetic repair on the front. A 3M™ File Belt Sander works really well to create the dish-out or valley area of the plastic repair, keeping the repair contained and keeping you working faster.
