Help, i want to cast some parts

I was looking for help on casting some small parts using sculpty as the mold. These are only vision blocks and other small parts. Is there a release agent you use when you pour resin? any help would be great.

Use suggested manufactures mold release ( they usually recomend thier brand name) or silicone. Check compatibility of “release agents”

I’ve read that some modelers use talcum powder for one-shot molds, and that many use petroleum jelly thinned with alcohol.

It has information on moldmaking and releases.
