So I guess my question is, what is "toast" exactly? I've used 3 year old poly with crunchies on the cap that was thick as molasses and it "worked". Granted I only did that making custom car stereo stuff that did not need to be structural. What happens to it? What properties does it lose or gain when it gets old. Obviously if you add mekp to it, it will still harden but clearly the end product must be deficient in some way. I'd just hate to toss 3 gallons of vinyl ester when maybe I could use it to make parts that are not as crucial as others.
