: Perhaps I was unclear. The fiberglass is delaminating from the
: wood, not the wood from itself. The wood is good. Its just
: bubbled forming under the fiberglass/epoxy, between it and the
: wood. I dont see this as being a wood problem, though I could be
: wrong. Seems more like an adhesion problem. The boat is at least
: 10 years old, not built by me.

: Someone suggested that it needs to be cleaned out and maybe sanded
: under the bubble, to remove the epoxy that has failed.

I'd more suspect that the glass never bonded in the first place. It's pretty easy to get air trapped under the glass. The bubbles need cut out with a razor, the edges feathered (sanded smooth so there's no sharp edge) then a new glass patch put in with epoxy lapping over the hole and the sanded edges.
