    Actually, polyester repairs on polyester boats are much more common then epoxy, Richard, by a substantial margin. Though we both agree that novices will be better off with epoxy. Or if strength issues are a concern, epoxy is the way to go.

    I stand by my over 40 Years of rolling out resin, position that you Can repair with Polyester, now with newer products some Jet Skis come to mind, I repair with Epoxy .

    After 40 years, you just might be considered a wee bit more then a novice Scotch&water.

    See, thats the difference between us. After almost 40 years of producing in Epoxy only (well 38 actually), I have to go for Vinylester on our largest designs (and I do´nt like that).
    But on boat repairs I cannot see any sense in using poly resins, not even a advantage in cost (when proper done).

    I envy you Scotch&water, I'm off to dispose of a 50 year old, 28' lapstrake power cruiser at the local land fill. It's a sad day and one I'm not looking forward to, but all boats come to this eventually. It's the right choice for this boat, but I still don't like it.

    repair

    i cant really comment from experience, but i have a copy of Hugo Du Plessis fiberglass book 4th edition, and quite frankly, frightened the beejesus out of me.
    All these old kit built boats that the bare hull did not get fitted out for a year or 2, the bulkheads glassd inonce the hulls fully post cured. :eek:
    I seriously wonderwhy I even dare go sailing in plastic boats!!
    some thing like 24 hours MAX after lay up, to achieve a 100% primarybond, after that even with conditioning the sanding hull there is NO Molecular bond only the "gueing ability of resin., and thats not good
    I have bonded stuff in my old boats with poly resin, but these where unimportant NON load bits, anything else-------epoxy.
