My little brother has a 99 laser red mustang. Over the winter he slid off the road and hit a snowbank, luckily doing no damage other than a large crack in his front bumper. Well, he got a new bumper off a 2001 GT a few days ago. He has yet to put it on, but he says it definitely looks newer than his and hes wondering if its possible to use some products to get his paint to match the "shineyness" of the newer bumper. Ive never done anything other than claybar/wash/wax so I have no idea. He got his car last fall and I'm fairly certain he hasn't even waxed it yet. I'm willing to help him out but I'm so new at any detailing that I'm just looking for advice. Thanks for any help.
