Try Willmann-Bell or Newport Glass or even Edmund Scientific. Anybody that is selling mirror kits usually will sell the grits or even the grit kits seperate. Unless you are making a very short FL mirror don't bother with the 80 grit for your 4". That stuff works very fast. At Stellafane this year, I took an 8" blank with a convex surface and in the space of 3 hours of work and talk, had a 36"fl. while I was getting others to push the glass for a minute just to get the rough feel of how to push glass. Have Fun and Keep Looking Up! Bob May
