I spent about 15 minutes polishing a used keg using my Porter Cable PC 7424 trying different things I had on hand like mothers metal polish and Pinnacle advanced swirl remover. It didn't turn out bad, I didn't take any before shots. Any idea what other compound I should use for aggressive polishing? Remember, it's just a keg, I don't want to spend a fortune. If this doesn't belong in this forum, please feel free to move it. I didn't see any other place that it would fit. I used Lake Country pads fyi.
