i do it the same way, i agree that little bottle is good for at least 5,000 cases, if not tens of thousandsI recently took the plunge and purchased the small jar of Neolube #2, it's graphite suspended in alcohol. I apply it with a small foam tipped applicator, got a bunch off Temu for cheap. I just get it lightly wet, and run it around inside the neck. I use a small desk light that is shining on the end of the neck, to verify I got an even coat as I spin it. Works great, and I can do it pretty fast on a batch of 100 at at a time. The bottle is expensive, but I thin it'll last me the rest of my life.
