Sealing Fiberglass Cockpit???

I am looking to caulk / seal the cockpit rim on my NDK kayak. What would be the best thing to use?



if you getting a leak because of seperation of coaming from the top deck, that needs repair by epoxy (mixed maybe with filler). If it is really separating along a significant length, you need to epoxy at least one layer of glass to strengthen the connection of coaming to deck.


4200 might work
Sometimes NDK boats get small pinhole leaks in the seams. My fiancee had one around her Explorer skeg box. We sealed it with epoxy. Our professional fiberglass fabricator friend said 4200 would work too.
