Wheels America tried tree times on mine as well. I ended up buying new wheels. Turbak (sic) polished mine first and they looked great but they could not reapply the clear coat. Wheels America polished them and then clear coated them, but the polish job was lousy and the clear coat has an orange peal finish. With the large flat surface of the Viper wheel it's very difficult to powder coat.
My suggestion is, if it’s not to bad, live with the curb rash, I wish I had never started with mine. I've spent about $5,200.00 since I started. I have my original with no clear coat and a second OEM set, with clear coat. When “polished” the set without the clear coat looks much better but it's raw aluminum and stains very quickly. The OEM doesn't shine as well but it always shines. It’s been an ordeal for me.
