I have been working on my boat and have cut a hole for a inspection hatch so I can have my anchor rope stored in the cabin and pull it up through the hatch and then attach to my anchor. However my bow is made of plywood. On the inside it have a thin layer of fiberglass on the out side it seems to be mainly gel coat, is there any other product I can use other the fiber glass resin to seal this wood, for example silicon (works in bathrooms) or window adhesive like sikaflex (urethane)
