Review on 🧪 Smooth-Cast 300 Liquid Plastic Compound - Trial Unit: Perfect for Testing and Trial Runs by Tonya Austin

When they say 3 minutes, they mean 3 minutes and not a second more. When I started pouring the second on my timer at 3:14am, nothing came out of the mixing bowl! The form I was able to fill out turned out to be perfect. Be careful if you want to fill multiple shapes or have a large object. a resin with a longer setting time may be considered. 😱Update: I did an experiment. I mixed metallic acrylic paint with resin. It didn't go so well! 😧 The chemical reaction was dramatic, expanding and bubbling over my shape dramatically. I hope to get out of shape. But I think the mold will fry.
