There are a couple of tricks my partner, Vicx, uses:
When there is corrosion on the aluminum, he sands the metal and sometimes even uses a dull knife to carve bumps and imperfections, then sands smooth.
He polishes with several different compounds; rough first and progressively finer.
The final mirror polish is accoumplished with a clean buffing wheel and light rouge. For smaller areas on windows, it's a Fordham wood carver with cloth wheel. For eyebrows and larger pieces, a buffing wheel on a bench grinder motor. (HF sells one)
NOTE: be VERY CAREFUL using the big buffer! It will catch the piece and pretzelize it, not to mention hurt a person.
NOTE #2: The Fordham Carver is a great little motor but will overheat if overused. It's designed to carve wood, so we had to rest it while working. It came with a flexible shaft and was hung overhead. A heavier duty motor would be better, but we didn't find one...
Nice work there Andy! I have always wondered what those hubcaps really look like. My Rod and Reel came with hubcaps like that, but they are so badly rusted, the chrome could not be saved. I still have them. One goes on the spare rim. The nice thing about these hubcaps is that they can clear some of the bearing caps that stick out far.
Chroming is very very expensive.
