Today I rotated my tires and took the opportunity to detail the wheels. After washing I clayed the wheels including the barrels. During polishing with a foam pad and M205, by hand, I noticed it wasn't removing the scratches/swirls on the polished exterior of the coated aluminum wheels. I tried a microfiber and Megs UC to no avail. It appears these swirls may be under the factory clear coat? They cannot be felt with a fingernail and the surface feels smooth. Has anyone else seen this on factory coated wheels? Or maybe I just need to get more aggressive with a powerball or flitz and a different compound/polish? I'm leery of removing to much of the factory coating. Thanks!
