Hi, conventional wisdom has it that one cannot apply polyester resin on top
of (cured) epoxy. The amine in the epoxy does not allow for even a partial
cure of the polyester resin.

Polyester resin and gelcoat will work over FULLY cured and cleaned
epoxy. It will not work over partially cured epoxy. Regardless,
polyester resin is not the best product for laminating fiberglass to
wood. Epoxy is far superior.
