-Spar doublers whether plywood or balsa sticks is an area where I would use epoxy.

I prefer to do most of my build's with CA but do agree with Ken's statement as it really is a personal choice and I do use the aliphatic resin's (yellow carpenters) on a few rare occassions.

However it was a releif to never agine have to use the cellulose cements a byproduct of paper manufacturing (Ambroid, Testor's UHUHart in Europe) and all the extra steps like double gluing and so forth as well as the hardening/cracking in a very few years. I suppose that was not such a hugh problem as the airplanes did not seem to last as long in those days at least for me.
