RE: gorilla glue vs. epoxy
A lot of modelers are using Gorilla Glue, but I haven't read any method of cleaning the junk off fingers. At least soap & water works with the carpenter glues and alcohol does the job with epoxy. Controlling the runoff on polyurethane is also problematic. I've used it, cursed it and watched it dry out, so I'll stick with the alphatic resins, CA and epoxies.
