Where can you buy mold making silicone or some kind of resin for making 2 piece soft plastic molds? I have tried the POP molds and the ones I did get to work didn't pick up as much detail as I would have liked. I have designed some swim baits and have master of them but don't want to have to ship the mold making material if there is something available locally. Does wal-mart, lowes or home depot carry anything that will work for this.
