Woah, you tried a lot. I was also considering the Nev'r Dull wadding, but when I had polished alum wheels several years ago that product faded back away quickly. I will give the quick detailer a shot. Thanks for your help.
Mine is so bad (just brought it home pre-owned) that I considered asking the dealer to fix it under warranty, but if it's real aluminum I completely understand why it looks like it does. I just figured it was "aluminum" look plastic.
