Just seeing if anyone has had similar issues. Twice today my spray nozzle has come off while detailing a car today. Once was with a 36 oz APC and got knocked down by an extension chord(spilled entire bottle. The other was a 16oz bottle I'd DS. Had hanging off my pocket, bottle fell and still had the sprayer stick to my pocket(also all contents were lost. I make sure to tighten these sprayers but they seem to work themselves loose.
