I believe most guys who hunt at those temps use no oil. I'd consider graphite, although if it's picking up condensation that may not be ideal either. By the way who makes Tri-Lube? And I would also put the bolt on the defrost vent if driving to another spot or if you have a rugged case, leave it in the box? Oh and what's the purported difference with this "extreme weather"? Some kind of Teflon?
Tri lube is an Outers product.
I'm still not sure what constitutes the "Extreme Weather" difference?
Edit:
Just saw Chucks answer.
Tupperware and stainless.
