Metku mods did a piece on polishing an aluminum shuttle case a while back. Well they had a mirror finish when they were done.

So I bought the polish thinking I'd do the same to some aluminum. Moral of story: dont believe reviews. They said that hand polishing is going to get a mirror finish (after wetsanding up to 1200grit) when really it'll take a buffer to get a mirror finish like they did.
I even poilished up to 2000grit (220,320,400,600,800,1200,1500,2000) and my results came nowhere near theirs untill I put it under a cloth buffer.
Even then the aluminum doesn't come out nearly as clear as their pictures seem to be.
After spending $40 on two bottles of polish, I'd say you'd be better off getting a plater to chrome your part for you.
