    shelf life of resin?

    Need to do some repairs to the boat. I have some vinyl ester resin, about a year old. Does anyone know if this or the harding agent has a shelf life. Thanks

    not sure if they have an actual shelf life, i've never seen one listed on a can. . . . i would definetly do a test piece, you will know if it is bad by how it cures . . . i have had old resins refuse to cure or cure in clumps. if the resin has went through a bunch of temp changes it may not be any good.

    Polyester has a shelf life on 6 weeks

    Just called my cousins husband and Vinallester has about a one year shelf life for perfect cure. He said to turn it over to get the hardeners to float up off the bottom again. Then do a test strip for sure and make sure that it not only hardens but also does not harden brittle. He said you are best buying new stuff.

    Put your best foot forward!
