I see PTFE formula listed for such products as 3 in 1 Dry Lock lube and
several others. So far I've been using little graphite tubes for door and
building locks - usually spraying it on the key, inserting and turning a
few times. The tubes very quickly run out of graphite and cost about $1.50.
I'm thinking of switching to the 3 in 1 product instead. Any experiences or
remarks before I do so?

TIA
