Review on 🔍 Nu-Calgon 4182-24 Gas Leak Detector Spray, 1qt, Blue by Sean Perry

Exactly what I needed. I found a leak in a fitting that eluded my efforts to locate. Simply spray onto fittings and valves. Thick so it spreads easily with a small brush in tight spots where it is difficult to spray. I covered all the joints in the suspect line with it as soon as I got it and after about five minutes I saw a tiny blister slowly form. I only lost about a quarter of a pound per square inch in 24 hours and that found it. I took this joint apart, cleaned it, applied fresh pipe lube, put it back together and my pressure test withstood the 15psi pressure test for over 24 hours with no loss.
