## Questions & Answers

**Q: Is it paintable?**
A: Cannot say. I bought it as a waterproof sealant and for this purpose it works perfectly.

**Q: Is this for 1 lb? Or for 10?**
A: 1 Lb. Was more than enough with plenty left over for other jobs

**Q: Can this be used to patch a hole in the wall around stove gas pipe?**
A: Are you talking about a gas line coming into the stove, I’d say yes it can be. If you’re talking about the actual stove pipe that gets hot then no.

**Q: Would this work to fill a 2 inch hole with electrical wires coming through it that is immersed in hot water?**
A: Yes, the only limit to this material is your wallet and imagination,
