"Does what it says on the tin. If you squirt some over a joint and there is a leak, myriads of tiny bubbles form and you can clearly see that there is a problem. Works on tiny leaks too. I have used it for car tyres as well as gas fittings and it works a treat."
"Located a very unusual gas leak at a capped supply nozzle on my cooker - did not expect to have a leak there as it has never been removed. This product identified, located and helped resolve this problem."
