At work we buy abrasives in quantities that you would not believe. Lately I have been using a 3M product called Micro Finishing Film, a plastic like disc that is 30 microns in size (gree in color) and some that is 15 Microns in size (Orange). I have a few questions about this stuff.
Does it have any use in woodworking? I use it exclusively to shine up Stainless Steel, but the stuff seems to last a long time and does not seem to load up much. Now what about cost? I am not a thief so I would not bring this stuff home, but if it works well on wood, I would buy a roll or two at my employers cost. (This is allowed). Finally what does the micron size equal to in terms of grit size. Since I use the stuff after using 400 grit paper, and before using the 1200 grit paper, I assume it is around 600 grit for the 30 micron size and 1000 grit for the 15 micron size stuff. Is this right?
(For the record, I do not work for 3M, or work where this product is sold. I am not endorsing it for wood, and therefore this is not a free ad for them. It merely works well on Stainless Steel, and I am curious if it works on wood)
