Speaking from experience with fields other than mirror grinding, I'd 
bet a nickel that shellac would be best.  It drives into a surface 
better than anything else I know, especially when diluted with 
alcohol.  A thin mix will soak right into plaster and then dry very 
quickly.  Couple of coats should do it (but don't use old shellac, 
which never dries right).

That's how the guys around here do it, apparently with no problems.
