air pockets(large) or bubbles(small)?? I had a friend tell me he had a bow that had air pockets the size of a dime, he drilled two tiny holes thru the fiberglass on opposite sides of pocket and then he put warm thin superglue in a syringe and injected it into the pocket using one of the holes, he said he could see the super glue "filling the gap" and when air space was filled and super glue was comming out the other hole he stopped and wiped off excess glue off of limb.. I'm thinking he used a 1/64th inch drill bit and had a couple of extras since a bit that small can break with little pressure. I have never made a repair like that so I can't say how well it works. I have warmed a bottle of super glue in a heating blanket and have also set the bottle of glue in a coffee cup with hot water in it. good luck with your repair, I'm gonna see what the other guys are going to recomend
