I'm on #1200 (5um) and keep getting persistent scratches, not very deep, like they come out after half hour of grinding. I'm thinking it might be the old grit sticking to (embedding) into the polyester resin that I'm using to seal/stick the tiles on (yes the resin is above the bottom of the tile) and despite scrubbing out the channels with a toothbrush they are dropping off and giving me grief. I'm going to give the tool another coat of resin to try and bury the monsters, but this means no more grinding for a couple of days while it cures.

There is an up side. The rest of the mirror has taken on a brilliant shine.
