Engine Casing Cleaning

It's getting warmer out and I'm getting anxious to get this machine on the road! Finally had some time to work on the bike this weekend. Engine - Cleaning Engine Casing: Before reinstalling the tank, I spent some time on refinishing the engine casing. The aluminum finish over the years has some discoloration and light oxidation. It's not bad but it certainly can look better. I have tried quite a few things on the metal surface with fair to poor results. I'm checking the motorcycle club boards now to see if anyone has some better idea's. In the meantime I settled on a treatment of Aluminum Navel Jelly and a finishing treatment of Mothers Mag and Aluminum Polish. If you haven't used Mother's before for aluminum work - I would highly recommend it. The product does an amazing job of bringing a luster up on metal surfaces. I'm got tired of polishing - lets mount some parts!
