Building a pontoon boat. Need to join numerous foam billets and cover them with something to reduce surface area. What would you do? Great stuff? EA40? Boat epoxy? Fiberglass tape? Pontoons are each 16’x1’x2’.

I have numerous billets of differing sizes. Thinking of joining them with dowels and epoxy and filling gaps with great stuff. Bonus question… Am I retarded? If so, why?

I had to ask because, in way of boats, I've never heard anyone say that barnacles are increasing the surface area of their hull, even though, yes, that's what they actually do.

If you want full on abrasion resistance then why not just go with the tried and true fiberglass with a gel coat finish?

Cost. I think.
Though I may land here
