There are several companies that repair wheels, some even come to your location. The challenge has always been that the crack itself can be repaired within reason, but you don't know what condition the metal is on either side of the visible stress fracture. In other words you may fix the crack and the metal is still cracking on either side of the fix. The key is to have someone that refurbs wheels do the job not a refinisher, the challenge is finding the right people with experience and the costs involved can sometimes be a bit more than some want to spend.
