Ok,
Thanks guys, I am looking at the epoxy thing but it will be a bit heavy because the plane is a small, .15-.25 Sig Tristar and needs to be as light as possible. I was thinking of using something like the 3M 77 spray adhesive. This could help me keep the weight down and have a good bond. But I also wondered what should I use to plug the hole that the contact cement made? I was thinking of getting foam chunks and putting it in there with some hot glue or even regular glue and tape over it?

Thanks for the advise!
