Dri-Lube. When is it a good idea, if ever?

[natman]

Unless your oil is specifically made for extreme cold, it's lying. Bone dry in extreme cold.

Once upon a time this was true. But it's the 21st century now, there are lots of oils that ARE made for extreme cold.

That white residue is likely graphite.

According to the MSDS for Hoppe's DriLube it's Polytetrafluoroethylene (AKA Teflon)

Looked at that sheet. Rubber disposable gloves for me, next time I use it!! Some nasty stuff there.

I assume it is inert once dry!!

That post taught me one thing:
Reading TLF through a monitor misted with coffee is still very possible!

Sorry
I didn't mean to make you have a Negligent Discharge

I assume it is inert once dry!!

It should be, and the Teflon will work itself into the pores of the metal

Nasal and negligent in equal measure.

It should be, and the Teflon will work itself into the pores of the metal

For me the difference of before and after applying the dri-lube to the trigger internals was instantly noticeable.
