The question was based on the adage "epoxy over poly, but never poly over
epoxy". I don't know how well polyester or vinylester sticks to plywood, and
it was just a question.

Polyester is a poor substitute for epoxy when you're bonding to wood. It
doesn't bond nearly as well. If one were to apply epoxy over it, you'd
still have a weak bond between the wood and the filler, which would be
the weakest link in the chain, so to speak.

If guys building boats or refitting old boats can afford not to budget the
funds, why bother with building or refitting? Why not just go buy the boat
they want?

Good question.
