It may have been mentioned and dismissed, but if so, I missed the discussion. So. my question is why not use polyester resin instead of epoxy for this process? Since we are primarily talkng about surface preparation for painting, and not necesssarilly about adding strength,wouldn't polyester be a good candidate? It cures faster than epoxy and does not warp the wood like water based polyurethane. Boats use it, why don't we?

Thanks.
