I have a problem.. whenever I roll my passenger window all the way down and then close it back again, the window folds out the rubber window molding behind the b-pillar, causing it to crease and damage that rubber piece. I've tried using a little WD40 to allow it to slide up properly but that only lasts for about a couple days until it starts folding outward again. Any idea what I can do to keep this from happening?

 

Silicon Spray. Will last far longer than any WD40.

 

WD40 is a degreaser. Its good for removing all the crap and junk but you need to "grease" it back up again after applying. Silicon spray like illlojik says is a good product to do this.
