I've never dealt with any Al car parts, but I'll toss in a little general knowledge gleaned from years with sailboats and electronics. If you've got a rough/textured surface you need to clean, blasting with an appropriately gentle media is the way to go. For smoother surfaces, there are aluminum polishing compounds; hit a sailboat store and they should have something. For a finish that's going to protect against future oxidation, I think anodizing can't be beat.
