Hello Guys! Hey, I've got a question about Polyester resin! How long is it's shelf life? I'm asking because earlier today, I mixed up some polyester resin for a suit of pepakura armor that I'm working on, and the resin is still a honey-like consistency! And I added the hardener as instructed!

    Actually, it eventually did cure! It must have been that the ambient temperature was below the recommended, retarding the curing process. It did kind of have a dark-brown color to it though!

    Glad it cured for you!  Most resins cure slower at lower temperatures, and faster at higher temperatures.

    Perhaps if I did this in the summertime, and started right after breakfast, I'd have an armor piece ready for it's next coat by lunch time!
