Many possibilities for product
polxc5,
In my short travels, I have had very good success with Wenol metal polish. There are two different grades and you may have lush with the fine version, but if you run into trouble with using, the stronger (read: grittier) version may be helpful. Another thing that I have had good luck with is with polishing heads, either a cone or a buffign disk. These two items, when attached to a drill or rotary, can really take some of the work out of polishing metal. Good luck and feel free to post back your end results.
