Great, thanks. There's a McMaster-Carr about 10 miles from my office
in Los Angeles, I'll drop by there and pick up some of the micro-fine
pads. Thanks for the tip!

What about after care, though? Presumably this abrasive will remove
the anodized layer so I'll have raw aluminum exposed to the elements.
If that's the case (and assuming the abrasive pads do the trick), what
can I put on it to prevent it from corroding from the oxygen and salt
air? Is maintenance going to be a problem?
