if your going to do it use a good paint like duplicolor or what ever it is. I painted me explorer rims black and have yet to have a problem with them, then again its a trail truck so it doent matter...lol
I didnt use a stripper either, i just roughed the surface with a brillow pad..lol like macco's 300 doller paint job. It held up decent even with the mud and everything else.
