The temperature is starting to drop here. It is hovering in the low 50F/10c. My trick to keep the laminating epoxy flowing is to set the jugs tight together with a heating pad tucked in between them and a towel over top. This keeps the epoxy flowing. So far the cooler temperatures don't seem to be effecting the other epoxy products that I am using. As they are pretty thick to begin with, I don't worry about if they flow or not.
