You might want to leave the room while they're working, though. I very noticeably bent two front rims on our 3-liter M3, and while the guys were working, I was reminded of that old saying about the ballet. From 20 rows back, it's clearly art, but in the front row, you can hear the grunts and popping joints, and watch the sweat fly.

Do not heat and hammer the bends. Even though it will fix the bend, it will weaken the wheel and much more likely bend again. If you want to avoid buying a new rim, and want to repair the bend, get it cold-rolled. It is a little more expensive, but the correct way to do it. Depending on the wheel and how much a replacement costs, I would consider this option. If you can find a replacement wheel for a few hundred dollars, id go with that option.
