I use the plain jane hobby glue gun glue stick, I do not do any prep to the shaft, I shoot CE.
When glueing in the insert I have a field point screwed into it, I heat the glue and apply it liberally, then I reheat the glue on the insert to get it into all the groves. I insert it into the shaft in a spinning motion. I then heat the field point near the shaft and wipe off any excess glue. Unless your shooting cinder blocks repeatedly this method works just fine and takes minimal time.
