I had the same problem in my van and used a product called "liquid
rollers". It's designed for bunk board carpiting on boat trailers.
These are strips of carpit that the boat sides on. It comes in a spray
can and is not an oil it's designed to makes carpited and fabric slick.
It's sold at most boat stores like Boat US and, Boaters World and West
Marine.

Anybody know of a quick fix for very squeaky sliding windows?  Ours
