Gorilla glue has a lot of uses or I wouldn't bother stocking it in my shop, I'm way too cheap for that. I just glued in a hard point, a piece of dowel in a balsa rudder with the GG. It expands and will fill in any slop between the parts.
There are no uses for Gorilla Glue that you listed, that couldn't be done better, faster, as strong if not stronger, and with less hastle....using alphetic, cyanoacrylate, or epoxy glue.
I can't even think of a use in modeling where Polyurethane type of glue is specific to.
