- Resin Adhesion to Molds Issue : Do not use a lighter or blowtorch to remove air bubbles, as this may cause damage to the molds, leading to resin adhesion to the molds during demolding and thus tearing the molds.

## Questions & Answers

**Q: How come I can't use a heat tool for popping bubbles?**
A: I think they are just afraid it will melt the mold. 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. Hope this helps.
