I think gelcoat is waterproof ,,paint is not and also any kind of glass eccsept epoxy !!!!!!!
Epoxy is the only waterproof stuff in that list and even that not 100% all alone.

Aren't the two-part epoxy paints waterproof?

Remember this is a Carbon Fiber Boat... You won't find a whole lot of flex at all...
Unless it´s put in an owen it´s not that nonflexing....

Some epoxy paints are waterproof and some are not as MikeyFin says
as for the bondo on the joint that was then faired...many epoxy products could do that and I'm sure they have their own brew of those.

You didnt mention epoxy your in paragraph thats why they cook it nothing to do with the carbon or was that to describe what happens to carbon in the oven?
You could build an e glass boat with epoxy just like you use vinylester with carbon but you usually wouldn't
or did i miss a post?
Cheers

Good stuff.
Of course, when discussing relative strength and stiffness of jointed composite structure (hull to deck) one must take into consideration classical matrix laminate theory in comparing the basic laminate properties in relation to the joint. It is nearly impossible to ever develop similar properties in the joint as with the base laminate unless you painstakingly interweave each and every layer in a proper proportion taking into account the tensile and shear properties of the plasticizing binder in an effort to match the original laminate, ensuring to employ adequate planar interface area between layers to achieve inter-laminar stress capability summarily equal to or greater than the constituents as proven by fatigue testing over the entire plastic to yield range. If not, that's where failures and stiffness problems will be realized.
When I was developing the vertical stabilizer to empennage joint for the Boeing 787 dreamliner, we learned a about the limitations of composite joints during fatigue testing. Proof is in the pudding.

Aviation grade epoxies cure to their fullest at approximately 275 - 325*F.
The problem with most epoxies is that they're only as good as the ultimate cure chemistry allows. If you cure at 160, and you're boating in the summer, you lose the majority of your capability when your structure is baking in the sun at near 160*.
Something to consider.
