Lot of guys swear by an automotive product, Mother's Mag Wheel &
Aluminum Polish.

The buffing wheels, speed, and technique are more important than the
compound used. Mothers polish reminds me of Brasso, and I never had good
luck with it because it loads the wheels and leaves black residue. I
usually cut aluminum with tripoli and finish with white rouge. Unless
you're going to do a lot of this type of work or just want to learn, let
a pro do it for you.

I wouldn't have envisioned the OP would use a buffing wheel on a 1½x2' plate.
Sure, that would turn a buffing wheel black. Mother's is not a product to be
used with a buffing wheel at all, rather it, like Brasso (which works just
great, I use it every 3-4 weeks on my brass belt buckles) is designed to be used
with a rag and your Armstrong polishing machine.
