Possible Great or Terrible Deck Repair

[fritzdfk]

Not too long ago I bought a project boat. Among many other issues there had apparently been some deck delamination issues. The deck is plywood core fiberglass. The boat had been covered up for 6 years or so and on the deck were quite a few areas with hard lumps of hardened foam of some kind. I asked the PO about them and he proudly described that he had drilled holes just through the top fiberglass layer and injected Gorilla glue. As you probably know Gorilla glue is activated/cured by moisture and standard procedure when gluing wood is to moisten both surfaces with water before applying glue.. As the core in the delaminated areas was wet the glue cured great and foamed out of the holes. I installed a 22" x 22" skylight in the deck and a opening hatch and no where have I seen any soft spots or delamination. The entire deck seems solid.
