I guess TPCE walks on both sides of the discussion; nice wood finished (semi-) exotic plywood on the inside, composite plastic on the outside.

The de Havilland DH.98 Mosquito is a British multi-role combat aircraft with a two-man crew which served during and after the Second World War. It was one of few operational front-line aircraft of the era constructed almost entirely of wood and was nicknamed "The Wooden Wonder"...When production of the Mosquito began in 1941, it was one of the fastest operational aircraft in the world...
QueticoBill wrote:Gorrilla Glue and Titebond Polyurethane are two familiar ones, as is of course PL Premium. A lot are sold as FRP adhesive and as flooring adhesive - especially wood floors. And I believe it cures or chemically changes with moisture as a catalyst rather than dries like PVA adhesives - Titebond II for example. Low priced - in the $30-40/gallon range - one part - and both trowelable and liquid for rolling.
It is what is used for stressed skin panels for stage platforms and acoustic shele products, waterproof, and just trying to understand if its a but for some reason for teardrops or just not explored yet.

...Epoxy will usually gel in a half hour or less. I wouldn't not consider the working time to extend beyond this, though it may take hours for it to get solid.
PLP in 28oz tubes @ $7 is ~$32/gal. $55/gal epoxy mixed with $15/gal silica powder is ~$40/gal, so not much more really.
