Its really simple... go to Adavance Auto Parts and buy RIM/WHEEL PAINT.. it has a picture of a rims on the canister... dont buy that cheap shit.. each can is about 5 bux, and buy the gunmetal paint, and they have rim clear coat... all together it should run you 15 bux or 16... you dont have to necessarily have to remove the wheels, you could tape up your whels w/ newspaper and tape... if your wheels have paint on them already i would recommend gettin Aircraft paint remover which is in the same aisle as the rims paint... spray the wheels down and then buy sand paper and sand them down... make sure u dont leave paint chips... once they are smooth its all easy from there.. lightly spray the rims w/ the paint, just dont keep the can upside down or facing downward for too long or else it start spitting paint instead or just spraying.. it shouldn't take that long, just make sure you dont over clear coat em... cause sometimes it will run..
