I've done some testing with regular luan sheets. I find that it doesn't
matter what kind of glue is used if you soak them in regular epoxy (west
systems or similar) since the epoxy soaks all the way through. I've boiled
test strips for 24 hours with no deterioration.

The "West" in West systems stands for "Wood/Epoxy Saturation Technique."
It's been used on boats for decades.

I use them as core for fiberglass, in place of foam. A bit more weight, but
cheaper, stronger, and easier to get.

To All:

A 'door skin' is a 3' x 7' sheet of 1/8" Luan plywood. It differs from
a regular four-by-eight sheet of eighth-inch luan ply because door
skins are USUALLY fabricated using waterproof glue.
Snip
When properly glued,
carefully varnished and religiously maintained, the common door skin
has proven to be a trust-worthy material for those of us who are flying
on the cheap.
