Not sure if this is the best place to share this or not, but just wanted to say that the super glue gel from Harbor Freight is surprisingly the best stuff I have found for gluing frags. You can get a 10 pack of 3 gram tubes for under $4, and somehow the nozzles on them seem to stay unclogged for a relatively long time. Most of the other little tubes i have used seem to have the nozzles clog after one use.
