Yea that's the reason I was asking about the pressure casting. I don't know what's goin on there. I'm gonna try a small mold when I start casting, just to see if it 'splodes or not, LOL. I figured if it works on resin, it should work on rubber. But from what the guys are saying here, it won't work. I'll let everybody know if I have to clean out my pressure pot afterward,
At least silicone won't stick to the pot, should just peel off. I know how it is, once you find a technique or product that works, you don't want to do anything else. It could be a waste of time, but hey what else is time and money for. I think vacuum de gassing is cool, I like watching it bubble up and then fall in on itself. And it definitely is the tried and true way. I think though that some air gets into the rubber when you pour it. Maybe the pressure is to get rid of that. It's an experiment, I will probably come back and say " I was wrong, it blew out of the mold, like She'ite through a goose", LOL. Thanks guys, I appreciate the feedback, Later,
