Casting in Polyresin is fairly simple. The problem come in when you turn them too aggressively and the skin pulls away from the resin. They can be a test of the patients. I've tried alumilite with no success and gave up to save the skins and resin. There are a few new resins out but I haven't tried them. In the beginning I was looking for something that would be easier to use, and turn but in the end I've concluded snakes are just one of those things you can't cut corners on and will continue to be a challenge casting and turning, at least until someone takes the time to find a new way. For me I fall too far behind with blanks I need to get done when experimenting. Good luck and I hope someone takes this further.
