3M makes what they call Micron-Graded Abrasive Finishing Sheets that
are very useful for polishing all kinds of hard materials on
irregular surfaces.  The abrasive is coated onto a soft, very
flexible non-woven backing (similar to Pellon) which conforms well
to all manner of surfaces.  The sheets are available in various
grits from 400 (30 micron) to 8,000 (1 micron).  They can be used
wet or dry.  And they hold up fairly well, even when forced to fold
and twist. Available through jewelry-makers suppliers (i.e. Rio
Grande, Albuquerque, NM, 800-545-6566).
