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

When used correctly this product is simply amazing. So far the only bad reviews I've seen have to do with people abusing the product. It cures very quickly (as it should), so start with small batches and work your way up. I used this product to harden a car helmet I made. I mixed two solutions and applied them with a cheap brush. It cured to a very hard coating and was not easy to bend. Be sure to read the instructions! If you mix everything together, chances are you won't have time before it sets and you'll be left with a useless brick.
