I decided to start the polishing process on the floor. That way the weight of the polisher was working for me rather than having to hold it in the air to do the work.
I had a simple polisher, seen in the lower corner, and used it with some heavy compound to get through the oxidation and small scratches. Then I used a medium grit to polish to a pretty good shine. It looked better up on the trailer than it did on the floor in the end. The aluminum is 60 years old and still, even though it is polished, has a lot of very small pits over the whole surface. But, all in all, it doesn't look bad. I will buy one of those two head polishers and do a fine polish when I'm through.
I put this as a separate page so I can write more about the products and the final polish work later.
