found another use for fluid film yesterday. i had a deadbolt lock which would not retract and after taking the outer covers off, i still couldn't get it to slide back. i went and got my hammer and a chisel, but then figured i'd try fluid film first. i sprayed the inner mechanism, let it sit a few minutes, and tried it. darn if it didn't work. i extracted the bolt, soaked it real good, and reinstalled it, works perfectly. before fluid film, i would have just bought a new lock because liquid graphite doesn't work for long, same with wd 40 and the other petroleum based lubricants. given fluid film's staying power, i doubt i'll have to buy a new lock anytime soon. that one use paid for the can of fluid film. thanks guys!
