A boatbuilding friend set me on the right lines when

any thoughts on the subject?

How do you keep the moisture out after the re-finish? None of the
gliders I have seen have any gel coat in the inner surfaces. Unlike a
boat, I assume the humidity is just the same inside the fuselage and
wings as outside.
