bubbles like crazy when a leak is found.

this stuff works amazing, I bought it for checking for refrigerant leaks on cars & it works great, it doesn't bubble up all over like soapy water, but when there is a refrigerant or air leak, it bubbles like crazy! there is no question where the leak comes from! definitely will buy more when I run out. it glows in a black light also which is very nice also!

Great at detecting small gas leaks.

Great at detecting small gas leaks. The florescent color makes it easy to see small bubbles, and the spray bottle works well.

Buy it, it’s worth it.

The media could not be loaded. Great product, shipping for a gallon is a bit high. Truck driver called to fix an air leak. He tells me it’s somewhere in the transmission and nobody can find it. I told him give me a minute, let me try this spray. Found the leak and it wasn’t in the transmission!As you can see in the video, he told me I’m the third guy checking and the only one that found the leak. Simple things like this It’s great for, I do wish people would leave good reviews with videos or pictures when you get a good product. As much as they leave a bad video of damaged shipping, that has nothing to do with the product.

Works, but needs a better foam method

Just squirting it on, really doesn't create a foaming I think needed to show bubbles. Just drops. I had to squirt into a bowl and lather it up and put on with finger for it to show bubbles.

Great Product!

I don't normally write reviews, but this was exceptional and warranted me taking the time to write one.I'm an independent owner operator of a 2020 Peterbilt 579, which is riddled with the ridiculous, cheap plastic push to connect fittings for the air brake system. I despise air leaks, and having to wait for my truck to build air pressure when I first crank it. My rule of thumb is if it can't hold at least 100lbs of air pressure for 3 days then the system needs attention.This is a tight standard by most. For years I have depended on soapy water solution and have even tried adding corn syrup. Now that I have found this, I will never use soapy water for anything other than finding tire air leaks. This stuff is hands down the most efficient solution I've come across. Within 15 minutes of opening the bottle I had located 5 air leaks on my truck that soapy water didn't reveal. It might be pricey compared to the alternative, but way more effective. I hope this saves another trucker like me some headaches. Way more important things to worry over than an air leak.

Really Works.

My shop air compressor, (with many connections and unions), had a slow leak. Sprayed this product on and found the leak on an unlikely connection. The leaking connection began to foam up, not big bubbles because it was such a slow leak. Able to wipe the solution away without leaving a mess. I'm left with a lifetime supply of leak detector.

Not thick enough

This stuff works fine, wanted to try another brand from that I usually use (Hercules Megabubble), which I get at my local Menards, but it wasn't as good. It is nice to have a large quantity though, as you can soak down unions/etc to be more confident in no leaks. The major down side is that its very liquid, and it just flows right off the parts.

Fantastic product ~ Much better than soapy water at detecting leaks

Sure, soapy water will detect leaks, but let me tell you, this product will find leaks that soapy water will miss.I had the opportunity to use this on my tire valves, and I discovered a minuscule air leak that didn't show up at all using soapy water. This product is fantastic; it detects virtually any kind of leak, and does so extremely well.Had I used soapy water instead of this product, I would never have known that one of my tires was slowly leaking air. The leak was so small that it required that I use a magnifying glass to see the escaping bubbles. With that said, although the leak was about as tiny as you could possibly get, it would have resulted in one of my tires losing a substantial amount of air over time.This stuff isn't cheap, but it is most certainly effective. Simply spray the area in question, and look for bubbles to form. You can either use the spray or stream mode. When I used the spray mode, I didn't see the tiny bubbles escaping from my tire. When I used the stream mode and a magnifying glass, the leaky bubbles became apparent.I consider this money well spent. It's a step up from using soapy dish water, and the convenient spray bottle will last a very long time.
