Interesting! I've used polyurethane (Gorilla) to glue together thin strips of ebony and satinwood to be boiled and bent, or to repair cracks in stock to be steam bent. It's ability to withstand heat and moisture are great qualities.
But it always seemed to have a bad reputation because of the foaming and messy cleanup, so I avoided it otherwise. For large or complicated glue ups I used urea resin - plenty of time and low tack. For veneering large panels in a big screw press I liked epoxy - even more time, no moisture added, and works in cooler temps.
So Michael, am I missing something?
