## Questions & Answers

**Q: Can this be used to air seal junction boxes?**
A: Yes, this silicone sealant can be used to seal junction boxes.

**Q: Any idea on how many 10.3oz tubes I should use for a chimney insert and top plate? Would 1 tube suffice?**
A: I purchased two and I based my decision on my experience of caulking tubs. Our fireplace is hand quarried stone so it isn't as uniform as modern built fireplaces. Also, Lee in mind, that I was using the caulk for fireplace glass doors and not an insert.

**Q: Can I use this to install stacked stone inside a metal firebox**
A: Not sure. It does work good as high temp adhesive though in my opinion.

**Q: Is this a non Petroleum based silicone? If so will it work with a cast iron boiler?**
A: Yes, this silicone is not petroleum-based and will work on a cast-iron boiler as long as the temperatures do not exceed 500-degrees F.

### ⭐⭐⭐⭐⭐ The best brand on the market!
*by M***D on August 27, 2025*

If you are a mechanic or work on anything that requires a good seal, this is 100% better than any brand on the Market! Better than Fords Grey, better than Permatex, this stuff is no joke. I have used it to hold metal center cap inserts on my 20s off roads 35inch tires. Held up in Midwest freezing temps. Used it to attach logos, seal electric boxes, my transmission gasket and anything I felt that needed to be adhered down and water right. High temperature and drying time is within 1 to 2 hours or even sooner. I buy this stuff like I do duct tape!
