the only thing I know that will handle polishing any frame of Titanium, Stainless, or XMetal to a high polished shine is Black Polishing Rouge for a buffer like used on car parts and stuff. A high speed buffer can give you the speeds desired (like a dremel tool for these smaller items) and the Black rouge blocks are for specifically for hard metals. I used it with a Dremel on some Titanium natural shafts for my darts, and they shined up better than aluminum! and pretty easily I might add...I will upload a pic soon to show you.
