You can learn more at the NW Propmasters Yahoogroup, take a look in
the Links there. I'm listowner of that group, too.

You don't vacuum it while it is in the mold; you put the resin under
vacuum to pull the air out, then pour it into the mold.

I buy most of my silicone and plastic casting from Smooth-On.
