Marty, like Grace I too if absolutely necessary, will use a thick pit filler (plate glass filler) to seal the large pit. However, when doing this I clean the large pit with my probe first to reomove the bulk of crushed glass. Once the pit is cured and scraped, I will then drill in the actual break area, as you can't drill thru the pit fill resin with great results. Tap a mini bullseye, and complete the repair. Once the repair is filled, cured, and scraped. I will (useing an old dull drill bit) drill/grind out the pit fill around the edges real good (on the large pit) apply some thinner resin ie: star, probe it in, ensuring every shiney part of the glass has made contact and been probed, then refill with pit fill and cure. The results are less cloudy looking, the repair always fills, and sue it takes an additional 5 minutes, but its my reputation and my customers satisfaction that matters the most.
