I've used an random orbital sander with a piece of terrycloth and Mothers to
shine large aluminum surfaces. Might be you already have the sander, so you
don't have to buy a buffer.

I'm redoing my boat. It's aluminum hull, painted. The gunwales are
unpainted aluminum, and discolored by stain, oily handprints, and
oxidation. What is a good product/way to shine them up, and what's a good
product to protect them and keep them shiny without a lot of maintenance
labor?
