ok so i saw a thread a while back about rattle canning the front bumper because of so much sh*t it goes through, and mine would be the king of that so i did it today. It covered up very nice but i put a couple coats of clear on because it looked dull, the can said wait 48 hours before using rubbing compound. Any suggestions on how to get the shine out and get rid of the dull look and rough feel??
