I just repaired and painted the rear, plastic bumper cover on my Honda van. I want to color sand and polish the bumper and rear fender to help with blending the color (new paint to old paint). Where the plastic bumper and the fender meet is a spot of concern for me. I am worried I will burn the paint at the edge because the plastic stands up just a bit higher than the fender. Not enough to see, but enough to feel. How do I buff this out without risking a burn on the edge of the panel?
I thought about protecting the high spot with tape while I buff the fender, then take the tape off and buff the plastic. Is there a better way?
