>What happens if the wood gets wet?

Dj,
The wood rots when it gets wet.  Keep it dry and it will last well
beyond your lifetime.  To keep it dry, seal every part of the wood that
comes in contact with air including plywood and spruce inside the
fuselage, wings, inside the spar boxes, firewall (both sides) and
especially bolt holes.  Preferred sealer would be the same epoxy you use
for glue and thinned very little with acetone just to get extra
penetration.  Don't thin the epoxy for glue joints.  Keep the sealed
lumber in the dark so UV rays don't breakdown the epoxy; paint or dark
spaces work well to keep the UV out.
FAA AC 43.13-1B Chapter 1, Section 3 has sound advice written in blood
regarding wood decay and sealing.
