I bought some stuff in a lot at an auction. Included were packets of "Imperial Diamond Lapping Film, grade 0.5MIC, 3" by 4" , 50 sheets, etc. by 3M.( have some 1 MIC grit size also.)
What would these sheets be used for, or how does on use them? -
Are they expensive items?
I would like to try them on something, - what?
Thanks. ( I know somebody out there on this group must know all about this stuff.)
