Normal polishing strokes (center over center, 1/3 diameter amplitude) tend to make a sphere. When all goes well, the surface of the mirror tends to become spherical, or very close to it. This is not different from grinding, only more precise.

Again, long grinding and polishing sessions are out of the question, finishing a say 10" mirror took us about 3 days. We prefer to spend more time on building/tuning the scopes itself, and obeserving of coarse. While grinding we only use 3 grits btw and do not clean in between them. Only for polishing we do clean of coarse.

The answer is simply "Flitz" polishing paste. Made just for gun parts it works like a champ, but they do advise to use some sort of solvent to remove all traces of the polish after you're done so as to not continue to work away at the metal.

Used Flitz polish on a .22 mop screwed in the front piece of a two piece rod so I could chuck it in a variable speed drill. Ran it as slow as it would go, and about six slow strokes per chamber. Cleaned them and put a swab of Birchwood-Casey Super Blue through them. Next trip to range was good, just a little friction.

Polishing cannot improve the dimensional accuracy or geometric accuracy of the workpiece, but is aimed at obtaining a smooth surface or specular gloss, and sometimes it is also used to eliminate gloss (matting). Mechanical polishing is a manual process performed on a single part, whereas electropolishing can be performed on multiple parts at once.
