When I had my Miata, I got some curb rash on one wheel. I got it repaired for $112. I think they had to use some filler, but you could not tell where the the repair was after they finnished.
It's a very simple repair. I'm doing my phone dials myself so I'm sure there are plenty of shops who can do a good job. Just make sure they use the right paint color and most of all they clear coat it like the original. They'll look good as new.
