It is great stuff, I've used it for the last 14 years, started out using it as a locksmith, the Teflon is a very very fine powder, the carrier in the can is actually butane, it dries off very fast leaving the teflon coating everything in the lock cylinder, its great for the pins in the cylinder. I've used it any many different things and never had any problems. it is a great lubricant, they also have a grease out that works extremely well also. As soon as I finish unpacking and find out where its at, I'll be using it to lube the gear on my locomotives and the tips of the axels on my trucks. I highly recommend it.
