I polish stainless (type 316L) 20 ga pieces with the 3M (fine) wheels
sold by Rio. I use no other abrasive before or after this finish.
The 6"x1" wheel runs about $41.00 and is worth every cent. I do not
follow with polishing, yet I have tested the polished finish using Zam
on a firm stitched muslin wheel. I think the stainless looks more
like chrome with the polish.
Have fun, Rebecca.
