I had a similar question about adhesives and polyester fiberglass. Specifically, I was wondering how well Gorilla Glue would bond with it? I want to re-do the landing gear block in a Kangke F3D-30 to accomodate a little different style landing gear, so it needs to be a good solid bond, and figured the foaming action of the glue would help to fill voids and distribute the load better.
