In Response To: Re: Epoxy pump dispenser question (Nick Schade - Guillemot Kayaks)

Like Nick said in an earlier post, once the epoxy crystallizes in a pump, it's probably shot. I caught a crystal of epoxy on the edge of my plunger seal. I didn't know it, and it sat that way for a month or so and deformed the seal. Even after a good cleaning, it was never quite the same.

Definitely keep the epoxy warm. Cold isn't necessarily bad for either the pump or the epoxy, but it's bad if the two are combined!
