RE: Best & lightest way to attach wing skins?
Tom, I use Elmer's Probond for attaching wing skins on foam. Follow the directions and you're set. By the way, I think it's much lighter and far easier to work with than epoxy. If you need more info. don't hesitate to email me. Take care and good luck. Hope its warm and dry where you are.
In Christ,
