That doesn't make them honest.
Shear strength of foam is rather low too. The main positive for epoxy is that it stiffens the wood. It does not bond to the foam very well, which is more of an indictment of the foam than the adhesive.

Sounds like the next ED remedy.
I haven't tried 800# glue yet. I've bought it twice now, but the first one died in the bottle.
They hold races every year now? $4 gas and distance sucks. $1.50 not so much, but the distance still hurts.

No comment from the snowy wastelands of the north?
I do what I do and it has worked for many years. Using epoxy and vacuum bagging equipment I build lightweight stiff wings that do not fold. I pass on the information freely. Do with it as you wish.

This what I do with a AJ/2 Q/40 wing
Make up my sheets and get them ready to place fiberglass on them. I use unie Carbon 1" on bottom. And a 5: 2oz glass over the TE, And last a full layer of 3/4zo glass to control the amount of resin I place on the wood.
This way I can really take off extra resin, I leave just the right amount of resin to wet the 3/4oz glass. In the top of the core I use .021"x.5"x16" carbon lam, vertical in the foam as my spar. Close and bag.
