A nasty stink, or Polyurethane. The Gorilla foaming type glue, and the Goop are Polyurethane, as well as the 6000 stuff. I recently folded up a wing with the CA glue, and flaming it first, and it worked well. I don't think I will bother with the other methods. I did use a few heavy duty paper type staples too, just in case. Just reading through the thread again. In two years, I have gone through another two houses, and not finished the Gnat yet. Pretty close though.
