This stuff is the shiznit. I spray not just my tires but I do my wheels also. It doesnt do much for the polished parts but makes the black areas look like new even if there is still dirt in there ( they are a PITA to clean ). I blacked out the rear housing and rear rails a while back. I spray that whole area also with the tire foam and it looks fresh as hell. I do the wheel wells and the frame wells at the side that you can see if you stand back a bit. This is what you guys need that have blackened out your wheels. I hate seeing your pics when the tires are gray and the wheels look as though they are covered with coal dust. LOL !! Butter them things down , Dude !!
