iam wanting to paint my wheels black or dark gray and im wanting some advice on a good product to use

 

My opinion: painted wheels NEVER look good. But, it's your truck so here's a suggestion:

Buy a can of plastidip black and spray one wheel. If you really do like the looks of it, then peel the plastidip paint off, prep the wheels properly and spray them with Rustoleum High Performance enamel. If you don't like the way it looks, peel the plastidip off the wheel and count your blessings! :)
