Re: mold making
I've done a lot of mold making, and I always use a parting agent. I use RTV silicone for my molds, and believe me, I've learned the hard way that rubber sticks VERY well to rubber!!
As for a parting compound, I've had great luck with simple vaseline, brushed lightly onto a mold-half. You only need enough to create a slight, oily-looking sheen on the rubber. I've never had a problem using this method. Alumalite also makes a purpose-made liquid that you brush on, and I'd assume it's a petroleum based compound, although I've never used it.
Don't try to pour the second-half dry, dude...not worth the risk!!
