Any advise or comment if I will use polyester and fiber glass on top of
cured and sanded epoxy on stich and glue? My plan is to prime the entire
hull with epoxy for a good bind before the application of
fiberglass/polyester skin.

I want to introduce this idea to the poor fishermen in the Philippines for
economic reason.

Polyester does not bond very well to epoxy. Most authorities advise
not to use this method.

The "old" system was to use thin polyester resin to impregnate the
wood. Then use polyester resin to "glue" it together. Many boats were
built this way in the early days of "fiberglass" construction.

I think I'd question your idea. Why not just use waterproof plywood to
build boats? It has been done successfully for years now and I would
guess that the Filipinos are well aware of how to build boats.
