Bought a pack of lapping films because they're cheap and I was curious after reading positive things on here.
It came with a nice big piece of glass and instructions to cut a piece of film, wet the glass, and stick the lapping film to it.
The films are completely smooth on the non-sticky side that's presented after sticking the sticky side (which seems to have grit like sandpaper) to the glass.
What the hell? Do I pretend it's got grit on the smooth side and it will abrade the metal properly with the grit from the other side?
Also if I stick a film to the glass, how do I use the next grade of film? Peel the first off and throw it away? I'm not concerned I wasted money because these were cheap and I have Naniwas, but I feel I'm completely misunderstanding how these work because I sense zero grit on the non-sticker side
