You may be familiar with "Wood/Epoxy Saturation Technique"
That has been used in boat building for decades?
How about "WEST systems" epoxy?
Yep - that's where the "WEST" in WEST systems comes from.
The wood gets soaked all the way through, so the wood is just there for
support, and it seems to last forever.
I BOILED some samples for 24 hours with no degradation other than a bit of
color change. Add light fiberglass over that...
