## Customer Reviews

### ⭐⭐⭐⭐⭐ Good for brass and propane
*by B***E on May 16, 2024*

Quite a bit in the bottle and many uses listed I hadn't considered.I applied this at 45°F on brass pipe and fittings and there were no gas leaks twenty minutes after applying, either by smell or soap bubbles. The weather here reaches -32°F in some decades.
