RE: Fiberglassing and epoxy

"Polyester or vinylester will not stick to epoxy."

Actually it does not stick very well to polly unless it is uncured , or very green.

THe USCG requires a polly laminate to be ground to 85% clean glass showing if more than a specific numbers of hours have passed.

SO the USCG is hoping the new polly will get enough clean glass to grab on to create the "secondary"bond.

Epoxy is far better at this , BUT be wary the hardner in most epoxies is unfriendly to skin contact.

Your allergy will build as more contact is made.
