My '07 F150 had beat-up emblems on them, and I gave them a coat of spray-can wheel-paint in the aluminum color. Not the ideal color-choice, but that's just what I had on-hand since I'd originally bought it for the plastic center caps, and it looked a lot better than the beat emblems. I used both adhesion-promoter and spray-can clear-coat. It held up pretty well. The toughest part of the job was getting all the clear plastic coating off of the original emblem. I got what I could off with a razor-blade in larger pieces, but I still ended up having to sand some of it down to blend in what wouldn't come off.
