A tip for a clean mirror polish.

Like you were talking about using finer grits on your belt grinder, but finer grit belts don't last for very long before they're clogged up and/or worn out. Get silicone carbide belts, they go as high as 3000 grit, you can wet them and when wet they last much longer. Get a small spray bottle and set it for a fine mist and put just enough on to keep it wet, but not dripping so you make less of a mess.
Trugrit carries 3000 grit and down 2x72 belts that are called "Norax Engineered Ceramic" and they have some lower grit Trizact silicone carbide belts as well.

I have found that wet grinding with high grit in combination with hand finishing with diamond compound I can accomplish a mirror polish twice as fast as the traditional way and I keep my lines sharp so they don't look buffed. Also by a happy accident I found that hand polishing with diamond compound I can get a near mirror polish with D2 tool steel, something impossible to accomplish with a buffer.
Just FYI
