Poly Glue ??
Yep, it's made by Elmers. Do a search on here for Pro-Bond. I used it for the first time to glue the stab on my S.E. I won't do that again as it expanded out the joint and was a pain to clean up in preparation to cover. I then used it to glue the Robart Hinge Points in. Again, the expanding nature of the glue dictates that you don't use too much and must make sure to get it down in the hole or it will expand back into the hinge knuckle. I'm going to try it on a set of foam cores as well as the retract landing gear blocks next. It is very strong, but I think it has it's uses.
