I very much appreciate the suggestions, however, I should have elaborated on the problem a bit more. There is a 1/4" square piece of balsa wood that is still very securely bonded to the hull at the top edge of the hull. The was was bonded to the balsa using what appears to be a somewhat flexible glue that easily peals off the deck. It is a semi-clear yellowish material that when sanded still gums up the sandpaper. Does anyone know what type of glue this is? Is there an epoxy that remains flexible after 10 years? I'm in the process of completely removing this material from the top surface of the balsa (to which it has bonded very well) since I don't believe I can find a material that will bond to it and the vacumed formed plastic (ABS?) deck. What I need is a material that will bond balsa to the plastic deck. Any further suggestions would be appreciated.
