Bumper Repair Procedure
After you sand the repair area follow these cleaning steps, they are the key in repairing plastic bumpers successfully. Use a gray or white scuff pad and scrub the repair area of the bumper or plastic panel with the cleaning agent first, a simple wipe is not going to work. It may work sometimes but may fail in others. Neon Bumpers may require two or three cleaning steps. The main reason a bumper repair fails is by not doing this step thoroughly. How do you know the plastic is clean? I use the water test. If the water beads up like a freshly waxed car or just disappears off the plastic, clean it again, then try the process again until the water stays there wet for a while.
