I am applying fiberglass on the bottom of my new boat (wood construction) and have finished one coat of E oz E-Glass with vinylester resin. However, after much research and the difficulty it is in canada to get vinylester resins, I would like to switch to the system three laminating epoxy resin and a second coat of E-glass. Has anyone done this before, mix vinylester and epoxy resins on top of each other over an entire surface? Does the surface between form a strong enough bond? I have tried to find the answer to this question but no concrete advise yet. Thanks for the help.
