## Questions & Answers

**Q: Could you do several layers or one very thick layer to create a rubberized coating on something?**
A: Absolutely, just please remember that the thicker the final coating is, the longer the cure time will be. We highly advise creating the coating by adding layers to the surface rather than just one thick coat.

**Q: Any temperature requirement?**
A: Flex Paste can be applied in a wide range of temperatures from 0°F – 150ۜ°F. Once applied and fully cured it can withstand a wider range of temperatures from -40°F – 200°F.

**Q: Can this be used to fix crack in small ref/frezer**
A: Hi there. Thank you so much for reaching out. Flex Paste can withstand low temps like that in a freezer. Although some customers have found success with similar applications, it has not been tested for its safety when coming in contact with items used for food preparation, storing, or serving. Please contact us if you have any additional questions. We're always happy to help. Flex On!

**Q: can flex paste be painted ?**
A: Yes. Must be fully cured before painting.
