It looks like that the Wood layer on the bottom of the board has released in an area of 2x5cm, it create a small bubble, whats the best way to fix it? By the way is their any fiberglas on top of the Wood.
In answer to your question, if its the same construction as my 2007 formula wood that I'm currently restoring, and I assume that all starboard wood boards are the same construction, there is only a very thin coat of paint over the wood on the bottom and nothing but the grip coat over the top where the wood is visible. No glass or resin whatsoever!
