I couldn't help noticing ya'll talking about the pieces rusting. Aluminum should not ever rust. If you have polished the piece, you should be able to just use Mothers polish or something similar to protect it. I have polished a few parts and they still look perfect. They do make a clearcoat because some polished wheels require no polishing, and they are aluminum. Good luck. It is all worth the work to me. All your friends will hate you for being so detailed with your engine. HA HA! Gotta work to look good. Unless your loaded.
