I still use a heat gun and haven't had any issues. **Q: Is a release agent needed prior to use?** A: I didn`t need anything to take them out of the molds. I'm guessing using a release agent will make them easier to release. **Q: Can anyone tell me if there is any deformation after receiving the molds?** A: No, they are well packed in the box without any deformation and the surface of the mold is smooth. **Q: How do you remove air bubbles in the resin if you can’t use a heat gun or torch?** A: Use 91% alcohol. It pops bubbles. Also you’ll have less bubble if you set your resin In warm water for about 10/15mins before mixing it. I either sit my bottles in a sink of warm water or I set my poured cups in a bowl of war water. DO NOT HET WATER IN YOUR RESIN.
