OK, guys! I'm not being clear. The air is not in the pit resin. The broken glass beneath the pit resin has black specks. Almost similar to what a crack looks like when all the air is not removed.

When we do a repair we use an injector so we can do a pressure/vacuum cycle to remove all the air. When you just add pit filler to close in a large pit opening (so that we can use an injector) we don't use a pressure/vacuum cycle, thus leaving some air beneath the cured resin. The pit resin flows around this air and traps it when cured. Keep in mind that I'm referring to smashed glass in the pit area.
