American Grease Stick Mz21 Mr Zip Graphite Puffer Gun

WORKS GREAT ON SOOOOO MANY THINGS! WOULD RECOMMEND! NO OILY, WD40 TYPE STUFF THAT ATTRACTS DUST AND DIRT. BUY IT!

It was mid-winter and my bike lock was starting to freeze up in the morning, with the key just sticking and not turning the lock barrel inside. I then heard putting this powder in helps prevent this so I decided to give it a try. I’m pretty sure it made a difference in a positive way, although I can’t be certain. Worth a try I guess.
