The rubber that hugs the outside of the window at the door top edge, thin/flat, almost squeege like piece, has gotten pretty squeeky as the glass rubs against it when putting the window up and down lately. Is there a way to lubricate this rubber without having some greasy streaks on the glass? (It is definitely the rubber-glass friction that is causing the noise)

 

Try some dry silicone spray on the rubber bits.

Should do the trick to eliminate squeaking and not leave smears on glass.

 

Thanks Phil! On my way to get some.
