Joy,

Looking at the Betsy Bay Kayak site clearly shows that the surface of the boat is coated in fiberglass.

"Our current wood/epoxy/fiberglass composite allows us to build kayaks as lightweight as Kevlar or carbon composites (lighter than plywood kits or DIYs), but tougher because of their structural core construction. While this process is more labor intensive than cloth/resin construction, the strength and beauty of the finished product is worth it. Our finishes are the best catalyzed acrylic/urethane products available and our kayaks require no more maintenance than Kevlar or carbon composites."

The description seems to indicate that they use unidirectional fiberglass, not cloth. Cloth will "almost" dissappear in epoxy, I don't know if you will really see a thin unidirectional layup (unidirectional layups can be stronger in a thinner laminate).
If there is discolored wood you really have to get the glass fixed.

Your best bet would be to get the boat back to the builder, if they will consider the work.

Maine is not very far from you, even someone from Texas knows.

Good luck
