I started using Elmer's Pro-Bond polyurethane glue in vacuum-bag wing skinning experiments last year, and my not-very-scientific conclusions are that the results are comparable to what I achieved with epoxy, so long as I worked fast and got the skins on the cores and everything in the bag within 10 minutes of starting to spread glue on the skins. The whole job was much less fussy to do, as there is no adhesive-preparation step, just squeeze the bottle and set to spreading the stuff on the skins. Anytime I set any lumber into a foam wing, like spars or landing gear bits for powered models, the glue stands out for its gapfilling ability and light weight. It's difficult to do precise slots and cutouts in foam, and the glue compensates for that very nicely without adding much weight in situations where epoxy would add a whole bunch of weight.
