exactly what I needed!

I was having problems with a mold I made from a 3D printed object with some very small details that were getting stuck and pulled out of the mold with the resin piece. Using the mold release completely solved this and I've reused the same mold (pictured on the right) twice so far without any noticeable damage.

Great product

This is the first mold release I have used, and I don't plan on using any other brand after trying this one! Really simple to use. My finished resin projects pop out of the molds so much easier with the use of this product. Will buy again!


Works great! Also helps keep my molds clean!
