I was looking at an old boat that had a plywood cabin. The owner/builder
had covered the plywood with fiberglass cloth. Long time ago. He said that
a surveyor who looked at the boat for insurance needs said that their was
too much water density in the plywood. The surveyor used some type of
device to test this. The surveyor recommended that the cabin roof be
replaced.

Question:: While I don't doubt that water got down under the fiberglass
cloth, I thought that if the fiberglass cloth was torn off and the plywood
was exposed then wouldn't it just dry up and then he [ friend ] could apply
epoxy and then new cloth but make sure that the epoxy has saturated the ply
surface and that way the ply could not get wet.

So, what about this problem.
