RE: anything wrong with carpenters glue for joining wings?
Tim I am not saying the fuel proofing does anything for joining the wings, I'm saying that's just another great thing about it, or it has many great uses. Such as fuel proofing or epoxying in the firewall... and I've NEVER had a part come apart that was epoxied, ever... wings, firewalls, horizontal or fertical stabs nothin.. I also love using think CA too but i just think epoxy has more uses and is stronger especially as you said with porous material
