Sounds like a great trick. I suppose a very tiny amount of graphite would work just the same as long as it doesn't ever work its way onto the glass.

OK - here is the "secret" to minimizing stuck filters: Before screwing it on, scrape some graphite off the end of a regular old "lead pencil" onto the filter threads. That graphite will lubricate the threads and HELP prevent seizing. If you tighten down like gorilla,nothing will help, but i have used this technique for 40 years or so and it really helps.
