"I recently stumbled onto a technique with rather surprizing results. I was working on a pocket knife with unstabilized wood scales that I really wanted to take along to the show that I was scheduled for the following day.
Once I had done the shaping and finish sanding on the knife handle, I applied an even layer of acraglass to the scales (these were red palm). Immediately thereafter I heated the acraglass with a propane torch being careful to hold it 10-12" away in order not to scorch anything or damage the epoxy bond beneath the scales. I first noticed that the epoxy thinned conciderably and shortly thereafter the scales started to bubble showing that the epoxy was replacing the air in the wood. Within 1-2 minutes the bubbling ceased and the remaining acraglass on the surface ( a fraction of the original amount) had dried and hardened. I immediately took the knife to the belt grinder with a 400 grit belt and sanded the surface smooth.
Upon finishing, the hardness was seemed to be similiar to commercially stabilized wood and the porocity had been eliminated. Bingo! Stabilized scales. Being a finished knife, I had no way of checking for total penetration but I'm confident that it was quite good because of the amount of bubbling that the scales had done during the heating process as well as the reduction in volume of epoxy on the surface."

- sounds akin to using superglue for a final finish. only agraglass should prove to be much stronger no?
