I've used mobile repair services twice (sorry, I'm in Houston but I'm sure they're about the same in your area). I think next time I'll try a wheel store, even though it won't be as convenient to get it fixed. Been where you are twice now with my S. Mobile services do an OK job but you can definitely tell the repair is there if you look close enough. Only way to avoid minor appearance defects might be to buy a new rim. Let us know how you make out! Good luck!
