RE: what to use instead of epoxy?
I have a Kadet Senior built with Titebond that is still doing fine with all joints intact after 25+ years.
These glues are good. I do use epoxy for heavy duty apps like firewalls and LGs and sometimes CA for tacking.
And white glues taste better when you chew them off your fingers. Sorry but never got over 1st grade. That glue was tasty!
