The bulwark/toerail (forgive me if my terminology is wrong) is made of teak. It is bolted atop the hull-deck joint. The gel-coat on the deck butts up to this teak and goes slightly up it about 1/2 inch. My problem is that over time, where the teak and deck meet, small cracks have formed and water is ingressing somehow. I assume the cracks have formed due to the flexing of the teak.
I would like to seal these cracks along the entire length of the boat using something very strong yet flexible-- like 3M 5200. I know that 5200 will bond to epoxy, paint, and other materials very well, but I also need it to bond to the teak. Hence, my question. Will 5200 bond to unfinished teak? Would I need to maybe put epoxy on the teak first, then put the 5200 over that? I have found that 5200 DOES NOT adhere well to Cetol! Will epoxy stick to teak?
