Seam sealing my spray deck?

I’ve noticed that I get wet from the seams in my spray deck while paddling flat water from the drip accumulation from my paddle and wanted to seal the seams to prevent this. I need to seal the seams on my hammock tarp as well and was wondering if I can use the same product. Anyone have any experience with this?

The same seam seal will help, but it will not make the deck water tight.
