    Is it possible to use the spray vegetable for a mold release?? If not, is there an alternative I can use in a pinch??
    Thanks

    I don’t use that but depending on what your doing
    Johnson paste wax or mothers gold carnuba wax

    Thanks for the response....I made a mold out of plaster of Paris and I intend to use a 2 part foam for my project. I was thinking I needed something like that spray to get down in the details. I don't know if I can accomplish that with wax you're talking about. I'm assuming that if there isn't some sort of release in the detail places the foam will stick there?

    Yes with plaster make sure it’s totally dried out first. You can seal the plaster with shellac, then wax it .

    You can use an artist brush to get the wax into crevices. Thin layer and let it dry.

  6. I love the wax angle on this. But if you find it's just not conducive enough for whatever reason to reach those difficult creases, PAM cooking spray contains silicone which will work as a release. It's not as good as wax, as too much can give you "greasy" surfaces to pull from, so be careful if you use it.
