window regulators and tracks
Lubricate works well too.
**edit** frickin spellcheck...meant to type Lubriplate
Lubriplate is excellent for window regulators and tracks as well. I used Lubriplate for this purpose for years until I switched to Sil-Glyde, which I had previously used for other things. Both lubricate equally well in this application, and possess good water repellency, but I now prefer Sil-Glyde, because it is easier and cleaner with which to work.
In the 1980s, I bought three gallons of Lubriplate 130-AA, which is an NLGI #1, calcium based grease, new and sealed, at a surplus store for $3.00 per can. I'm down to less than half of a can left.
I also picked up a couple of cans of this as well for $3.00 per can:

This is an NLGI #2 multipurpose grease, for automotive and artillery (GAA), made by Battenfield Grease and Oil, under NATO Code Number G-403 per MIL-G-10924D. I still have a partial can of this left.
