I wouldn't bother using glue at all.
The sleeve that holds the Glass Fibre flexi spars together is a compression
fit. I just ram it in as hard as I can, and then use PVC tape around each
end of the sleeve.

I leave it loose and tape a piece of 1/8" shock cord (bungee material) across
the junction. Easy to take apart, and self-reseating every time the spar
is relaxed. I can disassemble/assemble the spar without removing it from the
pocket. Makes for fast setup/breakdown. I haven't ever had one of these
come apart in the air. It *would* add unwanted weight to an ultra light
spar, though. I got the idea from 'self-assembling' tent frames, but couldn't
figure a good way to attach the cord to the inside of the spar. I'd hate to
drive a wedge or pin down inside the tapered spar -- it would exert too
much splitting force before it was tight enough to hold. Maybe glue, but
too permanent and taping (reinforced strapping tape) works well enough.


The best navigators are not always certain of where they are,
but they are always aware of their uncertainty. <unknown>

Thanks for the help all!

I tried a flexible epoxy intended for _some_ sailing application. I tested
it today and I'm up and flying. Thanks for your help.
