It has been a long time since I posted, but I have been busy grinding the mirror with 120 Grit.

It took much longer than I expected; about 10.5 hours of actual grinding. But I am happy with the end result. I can't find any large pits even with a magnifying glass.

Coincidentally, I spent the same amount of time on 80 Grit too.

Effort so far
Activity Time Calendar (2009)
80 Grit 10.5 hours June 12 to Aug 19
120 Grit 10.5 hours Aug 20 to Oct 5
