It appears that this was what originally was in the axis races. Avoiding an increasingly annoyed group of cows, the head was dunked into a muddy pasture. There is a precautionary tale here about view cameras and cow lots, but another time.
That was 18 years ago. I flushed it a bit with naphtha and tossed it into a box. Now I have a task for it. After taking it down, I replaced with white lithium grease (Permatex). Oh boy, it was as clunky as when it came out of the box from B&H. That has been cleaned out, and a bit of molybdenium grease placed in. Works, but I know there's better.
After Neewer hit the scene pretty hard with 'improved' gear to begin rivaling the old Spirotone wonders, I bought a video rail kit that included a focus follower. The friction grease in there had the perfect feel, but it was the crappy kind that creeps back. After contacting them, they sent me a small tube of replacement goo. Hooray, no creep.
They don't sell it and have not responded with an inquiry to send me some. I would really like to know what grade and make this stuff is!
