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.
Check this site out: [http://www.walcomaterials.com/main.html]
It has information on moldmaking and releases.
