Caulking?

[djpeewee]

In another forum we were discussing starboard and the difficulty in sealing it. It is an amazing product. The calking in the joints of our 28 is getting old. It is falling out in some places, mostly dirty with dark spots in other places. It is time to recaulk. What did the factory use as a caulking? Any idea? Whatever it is, it seems to stick OK to the starboard. I've tried Sikaflex, but it doesn't stick well enough. Has anyone found a product that works?

I use 3M 4000 UV. Not sure how it would stick to starboard though.
