## Questions & Answers

**Q: Does it become hard once set? Wanting to use as a mother mold**
A: It never sets - it remains soft and pliable. I would use hydrocal for the mother mold or reinforced fiberglass with epoxy.

**Q: Does this cure flexible or rigid?**
A: This product does not cure at all. It remains pliable indefinitely

**Q: Does this putty maintain its shape once molded, like modeling clay, or does gravity cause it to melt back down?**
A: Yes and it was very easy to work with. it did not stick to you hands and you could mold it very easy.

**Q: Wrap around outdoor speaker wire (binding post connection) for additional waterproofing? Want something removable for winter storage of speakers.**
A: This is potentially messy for that application. Try using E/FUSING 112 to wrap wires to protect them from elements.
