Thanks to this forum I learned about Premium Wheel (Roberto Avitia, 214-475-1729) in Dallas. I sent him a text with a picture of the curb rash (same pic as in this post) and he responded promptly with a quote. He came to my house on a Saturday morning and was able to repair in about 30 min from start to finish. The rash was on about 40% of the diameter of the rim and the cost to repair was $75. Roberto is very skilled at what he does and I would recommend him to anyone.
