Wil,

Sorry I can't quote the source, but, during manufacture the wheels were fully anodized then painted (which makes sense, it would be very difficult to anodize only a portion of a wheel). Painting over anodization is certainly an accepted practice in the manufacture of corrosion resistant aluminum products. Just FWI, after anodization (which has no inherent color, more of a texture) aluminum can be dyed (which is often part of the final "rinse" during the anodization process and, typically, gives it a "metallic" colored look) or painted (original Fuch's were actually dipped in paint). I don't know the proper "prep" before painting, but a call to any body shop should give you the answer.

Good luck,
