Maile 3 The molds were terrible quality, there were bubbles in them and some sticky residue. Then even after putting mold release, it was almost impossible for me to get the resin out without cutting the mold open. I tried without putting the mold release and I ended up having to cut the mold to get the resin out. Ive used this resin with over 100+ different molds so I am almost positive its not the resins fault.
