The theory is that the teflon particles will abrade the aluminum over time, but after using SS 50/50 on bare aluminum threads for many months with good results, I don't see how it would apply for this particular application; it would make sense in a high-speed/-heat machine scenario, but so little movement goes on with flashlight threads that it's not really an issue.
I see. I suppose that makes sense. I have to agree that it's probably not an issue with flashlights though. I've been using it on bare aluminum for over a year now with very good results.
