oh what to do with a leaky hull-deck cavity?
Hello, I recently got curious and dug a little trench on the inside tabbing of my hull-deck joint.
I found that there is a cavity about 1/4in between the inner flange and the deck behind the tabbing. I also found out that water came gushing through inside as soon as I started crashing through the waves (or vice versa).
Although I reglassed the trench, I am not too happy with having an aquaduct inside my boat . I was thinking on opening the tabbing at regular intervals to inject 5200 or polyurethane foam or (maybe even epoxy although I would need to remove all the humidity first).
Does 2 part polyurethane or 5200 adheres well in a humid environment? (Not soaking wet but with traces of water). Removing the toe rail with the nuts glassed in is too big a project for me if I intend to sail the boat anymore this season.
