I think we're not communicating well. I mean the track at the bottom of the glass that the nylon sliders move in. R111S may mean the tracks that the window slides in, in the front and the back, which I would not recommend lubricating at all. As for sources - your local auto parts store should have what you need. I have no idea where the grease I used came from - we got it 10 years ago at a flea market. - Eric |
