The Firing Line Forums - View Single Post - Best lube for plastic-plastic contact points

I'm working on my AUG trigger pack, which consists of a plastic sear with numerous sticky contact points against a trigger box made of the same plastic. What would be the most durable means of lubricating those plastic-plastic contact points?

I'm not experienced with plastic bearing surfaces, so I don't know what lube will "stick" and perform over repeated use. Looking around my shop I have on hand at least the following:

Militec gun grease
PTFE spray
Graphite (colloidal)
hBN powder
Smooth-Kote (which I think is a moly solution)
BP-2000 (which I think is moly-disulfide powder)
