Has anyone tried using dry graphite powder as lube for flashlights?
I had a tailcap that was feeling gritty, and couldn't find the silicone grease I'd been using. Came across an old tube of dry graphite powder, and thought, "Why not?"
Used just a tiny amount spread across the length of the aluminum body threads, and after tightening and loosening the tailcap several times to work it in, I'm impressed.
Turns much easier now, and feels very smooth. I expect it'll last longer than silicone grease, too.
