Actually, I always recommend nitrile gloves when working with epoxy. Hands sweat and while biohazards won't go through latex, that I know of (?), chemical can. The sweat can help communicate chemicals in hardeners and other boat building chemicals through to your skin, and solvents can go through latex as well. The place to look for Nitrile gloves is your local auto parts store. If they don't have them, look to your local supplier for auto body repair shops. Buy the stretchy ones, not the silly clear plastic ones that fit loosely on your hands, and greatly prefer those that go up your wrist a couple of inches. When reaching over long sticky surfaces, wear Tyvek sleeve guards. If you, like me when I was living in Fairbanks, can't get nitrile gloves very easily, at least look for heavy-duty latex ...not the drugstore type that your doctor uses with that little tube of silicon lube that nobody loves. Same rules for the gloves going up your wrists a bit.
Just my 2-bits. I go through a lot of gloves.
