So I decided that I wanted to polish up the aluminum on my Tracker Pro Crappie. Ive done a few test spots and the difference is huge! Using 3M Marine Aluminum Restorer and Polish, buffing pad, and 3000 grit sanding pad. Tried just using the buffing pad to polish it, but there was still some pitting spots. Used the 3000 grit sanding pad and polish, which easily smoothed the pits out and after buffing it, it left a nice shining finish. It'll be a lengthy process, but the results will look good I believe.

Here's a few pics.

What it looks like before polishing. Mainly oxidation and water spotting with some pitting.
