Some people confuse polyester resin with epoxy resin; but you could be thinking of polyurethane over epoxy which is (one of) the ways to protect epoxy from UV damage - but the poly is there just to keep the UV off the epoxy; it's the epoxy that's doing all the waterproofing (and by waterproofing, that's 'build it with no structural fasteners other than epoxy and sail it in the ocean for 20 years' waterproofing, not 'keep some splashes off it' waterproofing)
