Ken, that makes perfect sense. The first application appears to seal the wood especially since glue will really penetrate an end grain cut. Then the rule of only use just enough glue to do the job would apply once again. There is always that balance of not too much but also not too little. We need to have some glue between the parts being bonded for maximum strength. At work we sometimes will all glass beads of a certain diameter st that when the parts are clamped together for curing we will have a bond line of adhesive the same thickness of the glass bead diameter. When we CF wind SRB cases we have points where we measure the resin content in the fiber strands. Too much resin creates just as many issues as too dry.
