If you are talking about the corrosion pits from salt and such (the reason I do not let tire places put wheel weights on the outside lip of the rim) then you will need to sand them down, polish them and repaint. The thing I used when i did my crx rims was a 3" Roloc pad on a die grinder. If you use it though, you have to be real careful not to take off too much material from the rim. You could also use a scotchbrite (3M) pad and do it by hand. Once you get done, make sure you wash off the rim thoroughly before painting and dry it off. Mask off the tire and valve stem so you don't get any overspray on it. Then give her a few good thin coats of paint to get a good finish. After it dries for a day, spray clearcoat on it to seal it up and give it a good shine. Make sure the clearcoat that you use is for the type of paint that you use. Otherwise it could bubble up on you.

If done right, the rim will look brand new.
