Thread: 3M Micro Abrasive Film, A Usage Guide and Review

Jordan,

I'm not sure where everyone else is getting their abrasive sheets from but I bought mine from Lee Valley Tools as I have a store in our town. These are 3M mylar abrasive sheets, available with or without adhesive on the back.

Polished marble or granite tiles are generally quite flat (the process in polishing is the same as surface grinding) and can be had by the piece from Home Depot and the like. Regular terracotta and ceramic tiles are NOT flat enough.

For rust removal and sanding blades, I'd stick to the common wet/dry type papers.. cheaper and easier to handle, the mylar stuff will work but I can't imagine it being any better and it has to be cut rather than just fold and rip the usual stuff.

As for longevity, I've used it but switched to hones and haven't looked back since... I'd not hesitate to use these sheets if my hones weren't available but seeing they are I've never wore one out. If you are thinking cost vs. performance, the sheets will get you in the game cheap but if you stay with it, hones will come out on top in the end.

Regards

Christian
