I saw on some site, that the luthier labled his sandpaper on the side with tabs. I just ordered a new set from 80 to 3000, and this works great with a spray bottle of water (was using olive oil! But it gunks up with time)
Question:*About how many strokes, on average, do you take when you get into fine grits? I know each succesive grit takes it down to that grit, but to put less wear on the wet/dry paper, when you get above 400, what is the minimum for an average blade? Does anyone have any general rules?
*And does the fine stuff wear out/clog quicker?
