Check with your dealer or a good tire shop like Discount Tires. There are companies in some cities that will professionally repair and paint the damaged rim. A few years back Discount Tires accidentlally scratched 3 of my rims when mounting new tires. A small pebble or something got inbedded in their tire machine. They said they'd pay a local wheel repair company which many of the dealers use, or I could choose any wheel from their catalog as free replacements. I took the replacements and sold the stock scratched rims to someone who needed them for snow tires.
