Hey Everyone! I'm trying to find ways to save time, money, etc when I do large runs. I'm shooting up to 15 molds at a time, but am getting sick of having to reheat plastic via microwave when shooting thr molds for a second/third time. Sometimes I burn it if I'm not paying close attention... :S......I see some people use a presto pot, but does that work better? Does plastic need to be continously stirred if using a presto pot?
