Hi all, my wife and I just looked at a 1986 Compac 27. What are the decks cored with on these older boats? It has some deck leaks I think can be repaired by rebedding all the hardware but I worry about moisture in the core. This boat needs a good dose of bleach to clean out the mold and mildew but the hull and rudder look fine (to me). The deck looks great also and sounds great when I rap on it. Any advice for the newcomer? I'm all ears...
