Will West System 2-part epoxy freely release from a small silicon mold? I've got some left over from my table project and want to make granddaughter some pendants.

Another option is to call West System and ask their opinion. Yesterday, I bought new vulcanized rubber tires, for my bandsaw, from Carters. I wasn't sure if G-Flex 650-8 epoxy would adhere to vulcanized rubber, appropriately, hence I might have to order Carter's 3M epoxy. I called West System and asked their advice. I was assured the G-Flex would work, appropriately.

If you know some specific info about the silicone, I suppose that would help with West System's advice. I would think they may know what's best to apply to the mold, to allow for release, if need be.
