Epoxy on soundboards

[Don]

Hi Dean,

Just because epoxy is "water proof" does not mean that it is "vapor proof".
You may be able to raise the partial pressure, or slow transfer of water
vapor, but eliminating it by coating wood is probably a futile endeavor.

I suspect that the "better tuning stability" may be simply an almost total
lack of crown.
