In case anyone is interested in epoxy and fiberglass mold making, we taught a course at the Stan Winston school on it. My lead mold maker, Mike Cooke did a great job explaining our process. It’s definitely a valuable class if you intend to start casting in silicone.. and if you wanna see my dumb face explain the casting process, you can check out part 3 of them. As always, the SWS offered a free 7 day trial.
they are probably the best program around and I highly recommend them. It was an honor to be asked to teach
hope this helps anyone interested
