I'm going to give Dr ColorChip a try on a couple chips on the front bumper cover. On one the paint balled up ( both color & clear ) on the edge of the chip making a "bump" on the back edge of the chip, it must have been a glancing blow. What is the best way to remove this bump without causing a lot more prep & maybe finish work? I like the quick and easy way this system is supposed to work! I may just leave it as is if sanding is needed. I attempted wet sanding years ago and well it's a long story but the paint shop appreciated my business! Thanks!!!!!!!!!!!!!!!!!!!!!!!!!
