There are advertised wheel repair places. I have curb rash as well, but I figure the only way to fix it is to machine the lip and recoat the wheel. I never fixed mine because i figured that the wheel would be uneven. Two shaved, two orignal, etc. Machining is pretty easy though because of the circular design and material that the wheel is made of. I agree with the previous post. Take the wheel and smooth it out. You'll most likely have to apply the coating carefully without getting the rest of the wheel.
