Hi Logan

Frustrating I know! But at least it's right at the beginning of a finer grade abrasive. A couple of wets at 120 will remove them quickly. You might even be able to grind them out at 320 but I think you'll find it quicker with 120.

Bill is right. Be careful how you lift the mirror off the tool. When you start a wet, gently place the mirror or tool on top and make a few very short strokes with no pressure. This helps reduce the size of any larger bits of grit.

Scratches look ugly but even if you have a few on your mirror at then end they make almost no difference to its performance. I would get rid of these since you are only just out of rough grinding but if I had a couple at the end of fine grinding, I would just leave them.
