RE: Preserving Gorilla Glue?
MajorTom--I have been using a short pieces of plugged fuel line as a cap for CA glues. I seals well and does not let air in. Don't know if it would seal a PU glue bottle. They may be too large, or perhaps a piece of large fuel line would work. I use vasoline on the threads of Goop to seal the tube, otherwise the Goop hardens near the top also making it unusable. or at least very messy if the tube breaks at the botom. Vasoline on the threads of the gorilla glue may keep a better seal as well. I think we are on to something!
Thanks to all that responded.
BTW--Goop is great for glueing on canopies. Sticks like crazy to monocote or ultracote. No need to cut covering and glue directly to wood. I use an acid brush to apply a thin coat to the edge of the canopy and just stick it on, hold down with rubber bands and/or tape. If you get any on the outside of the canopy or the planes covering, use alcohol to get it off before it dries or you'll never get it off.
