Next on the list, we've got yet another agent that manages to win our hearts. It's the smoothon epoxy release agent and it's widely considered as one of the best convenient agent you can buy. While this product is effective for its intended purpose, this release agent is an extremely volatile aerosol. It will release mold rubbers (such as polyurethanes and polysulfides) from properly prepared models. It does have a smell and you're not supposed to breathe in the fumes (work in a well ventilated area per the instructions) but the smell isn't unpleasant, just strong, and it dissipates quickly. It just makes for easier release of cured resin.

It is easy to use, and when the epoxy resin cure time is up it slips out of the mold like a glove.
