Tip: |
I found a cheap RTV silicone invarious store's auto departmant. It's for making/replacing engine Gaskets and it is great for molds. It dries strong in a day. It comesin a squeezable tube like toothpaste and costs around $10. You can get 6 molds or more out of the RTV. I only use it 1/4" thick. Its strong that thin, but I also reinforce it with plaster or Ultra cal 30. I recommend when making a two part mold use Vaseline as a mold release. Nothing sticks to it. |
