As of 2018, all molds come standard in the blue silicone molds which work for all resins - polyester, urethane, or epoxy. Pink versions of this mold will only be available while current supplies last.
Mold release sprays help to extend the shelf life of our molds. We recommend Stoner Themoset for Polyester and Epoxy Resins, and Stoner Urethane for Urethane Resin.
