Help! Epoxy replacement for laying fiberglass?

[MaxTheFliteFreak]

I am building a semi-foam/ balsa glider kit and it's going great, except for the faxt that I don't have foam safe epoxy, which is needed to lay down three strips of fiberglass down the centre of the wing. I do however, have foam safe CA, which I have used as a substitute for epoxy on some of the foam parts. The one thing I am uncertain about is laying down the fiberglass strips, because my epoxy melts foam. I would just get foam safe epoxy, but I cannot get that from where I live and it would take too long to import. Does anybody know if I can use the foam-safe CA or use anything else that I might have at hand?
Thankyou in advance, happy flying!

Clear Gorilla Glue is foam safe, and should work. I've used it on most of the foamboard planes I've built. Not sure if it is available in your region.

Gorilla glue may foam and cause a mess.

Hard part is your looking for strength you could use something like wood glue, install let the glue dry and add extra coats to help fill and strengthen.

Thankyou very much! I will definately do that. I will see if I can get Gorrilla glue, and if I do, I'm sure I can wipe away the foam and recoat if it's too thin. I appreciate the feedback!

CA will work, I’ve used it on small parts. Polyurethane also works well, the same stuff used to put a hard finish on furniture.

These other products will work but I suspect epoxy will produce the strongest part.

CLEAR Gorilla Glue is the key factor here. It's non-foaming. The regular brown, or white gorilla glues will foam like crazy and are not what you want.
