RE: Gluing question
Btw, epoxy is also nasty when it comes to allergies. I've heard that it's not a question of "if" you will become sensitive to epoxy, it's only a matter of "when" and at what doesage. Some people react sooner than others.
I use the polyurathane (probond, etc) glues a lot, and I really like them. I haven't had any problems, and I haven't heard much about problems, but I'm sure someone out there is allergic to them. It does have a funky smell that my wife hates, and it does feel nasty on the skin, so try to keep it off the fingers.
