Another take on this that maybe makes me come off less like a know-it-all. After reworking the window regulators on the '68 I used to own back in the '80's, I used amber wheel bearing grease as track lube. Because that's what I had. Worked great. Sometime after that my company got a three month contract beachside and I took my car. (Off-season, cold and windy.) A few months after I was disassembling those tracks again and cleaning every single bit of that grease back out again and replacing it with lithium. It was not fun but I kind of needed my windows to roll up and down. On the bright side, that was back before I learned that Ford's nasty black "moly' EP grease was the best chassis grease around.
And in case you didn't read between the lines there- sand. Lots of it. I traded off that car like five years later and sand would still sometimes fall out of the doors/rocker/trunk/whatever when you slammed the door. All our work trucks were the same way.
.... it wouldn't be the first time reality took theory and conjecture out behind the woodshed and gave them a good thrashing.
I have some cars. With a long list of parts on them that if anyone was interested in, they'd ask.
