Review on 🔬 Smooth Cast 320 Liquid Plastic - Trial Size: Explore Quality Mold Making with Ease by Morgan Gilmore

I use Smooth-On silicone molds for small movie prop replicas and this resin works perfectly every time! And they are easily removed from the molds without the need for a mold release agent. Don't forget to mix the pieces quickly because you only have 3 to 5 minutes to pour the mixture into the mold before it turns from a buttery consistency to rock hard! Virtually no smoke and fast curing time (15 minutes) allow castings to be removed all day if needed. The last detail is well polished and varnished. Highly recommended!
