Yeah.. I had my RS wheels Powdercoated.
I found a place locally that did it for $65/wheel
Way cheaper than buying new rims. The only problem was I couldn't find a company that would powdercoat and remove the wheels so I had to put my car on jack stands and take all the wheels off myself then get a friend with a truck to transport them for me. If you're lucky enough to find a company that will do both then it will be much easier for you. all in all it was definitely worth it!
