You would have to get them media blasted I believe. At that point with repainting or powdercoating it's probably a good bet to just keep looking (figure on the low end another 100 per wheel for paint or powdercoat and that probably will not include prep, unless you have a hookup).
I like the wheels. The finish may or may not go well with your FX. It really shouldn't matter what we think, it's your ride!
