Please note I never said the epoxy repair would not be stronger than the
same in polyester. Lets take this to the extreme and say epoxy is 100 times
stronger and many think this is the case. Why on a 25 year old boat would
anybody want one side to be 100 times stronger than the original deck. I
think I did mention proper workmanship counts which precludes contact
cement.
No doubt Matts repair will be stronger and probably prettier than mine but
strong enough is strong enough.

All this puts me in mind of patching an old goatskin water bladder with a
piece of new leather.

Also, cost benefit analysis, proper surface preparation, who knows what?

All ties in with chemical bond curing. How about contact cement or other
"primer" over old poly, followed by more poly / glass?
