Then I move into some jewlers rouge moving to finer and finer rouges. The polishing compound comes last and is basically for final cleanup.One thing about polishing metal that I have learned is speed. You really can't do a good job with a drill be it corded or cordless. They will work, but you will never get that really nice deep shine. I use a variable speed electric die grinder. It does up to 25,000rpm and works great. It's just bulky but that's not an issue if your working on a bench.</blockquote>
