## Questions & Answers

**Q: How is this applied? Does it have a small brush in the bottle?**
A: Yes. There's a small 'dauber' attached to the underside of the lid. It isn't strong, so use carefully.

**Q: Does this detect natural gas leaks**
A: Yes, even low pressure gas leaks will still bubble up. Be sure to cover joint completely and wait a few minutes to check for bubbles.
Bigger leaks should show quickly.

A: Possibly

**Q: Will this freeze if I leave it in my truck in the winter?**
A: Well, I live in New England and has never frozen up on me
