For the uninformed like me.
How are Frontier different that Scotch Brite ? I keep Scotch Brite in lot of different grits on hand for general shop work. Fine ones clean nice with no scratching. White one is listed on 3M's spec sheet at 1200-1500 grit equiv.
Is Frontier made out of a different material ? What do you figure the grit rating would be.
