## Questions & Answers

**Q: Any idea why some spots didn’t cure? Several parts left liquid under the skin. Any way to fix this?**
A: Mix materials separately then be sure to mix thoroughly when combined. If that doesn’t work, your material is likely old or has been exposed to air and the separate parts have solidified in small areas.

**Q: What specific items come included in this “kit”?**
A: Two gallons of material. One part A and one part B.

**Q: Is it thermally conductive?**
A: No

**Q: Can this be used for making molds for resin?**
A: Yes. But it will Ned a release agent or the resin will stick to the mold.
