RE: Gorilla Glue
On a balsa sheeted foam core wing where I did not do a good job of sanding the dihedral at the center, I glued the wing halfs together at the correct dihedral and let Gorilla Glue fill the gap. I have also used it to glue an ABS radial engine front and back together where the Gorilla Glue filled the cavity in the engine; it added strength and weight. I have not had good success with using it to glue hardwood to a fiberglass fuselage in a gas plane; the joints eventually vibrated apart.
