How is this applied? Does it have a small brush in the bottle?

Yes. There's a small 'dauber' attached to the underside of the lid. It isn't strong, so use carefully.

Does this detect natural gas leaks

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.

Will this freeze if I leave it in my truck in the winter?

Well, I live in New England and has never frozen up on me

It did leak a little in shipping but still a wonderfully functioning product.

Great stuff. Easy cleanup. Will continue to bubble a long time. It's did leak in shipping a bit. Much better and safer than any homemade soap solution.
