"Great product but squirty spray makes bubbles anyway. I used a small paintbrush to flood round the compression joints when I capped off an old gas hob supply. Confident that there are no leaks - even tiny ones"
"It's like thin washing-up liquid. Only problem I found is that the sprayer introduces small bubbles in the fluid when applied - these make it difficult to see tiny gas leak bubbles. Still it found the leak."
