after a week or so of using fluid film, all my techs love it. it has become their first choice for freeing rusty/stuck bolts, removing corrosion from battery terminals, lubricating taps/dies, and lots more. they all said their favorite part is that it is not a runny solution like all of the other penetrating oils out there. they can spray an object and don't feel like they have to keep spraying it because of gravity taking effect, in turn, using less product which saves the company $$ (and helps my end-of year bonus ) i highly recommend it to anyone who does maintenance/repair work in the automotive field or the green industry. keep up the good work guys!!!!!!!!
