They fill the damaged parts with metal, and then repaint the entire wheel. It cost me about $175 for the wheel. My dealer did an excellent job on it, and it looked new. I need to get the same wheel repaired again.

BTW, it should take a good couple days (3+) to fix the wheel if you want it done right. I got my dealer to give me one of their 20's (different style) while my wheel was being repaired.
