Question:

I have a couple of mid 90’s BMW 3 series whose window weatherstripping is binding and squealing a bit.  What’s the right product for lubricating these? I’m pretty sure any petroleum-based lube or silicone is going to smear on the glass.  Is graphite appropriate, or is it harder than the glass?  What else is there? I’d rather not replace the weatherstripping since it’s OK otherwise.  Worst case, does anyone know where I can get replacement 3 series weatherstripping for a good price?     Randy — Randy Crawford   http://www.ruf.rice.edu/~rand   rand AT rice DOT edu

Response:

It sounds like you need a tube of gummi-pflege: http://www.nmia.com/~dgnrg/page_9.htm Note, there’s supposedly a nationwide "shortage" of this stuff at BMW dealers (or so they say). Get down to your nearest dealer today….

At work, we were told to use radiator antifreeze to lubricate any rubber weatherstripping.

Response:

Gummi-pfleg is BMW’s recommend product, but almost any spray silicone will do the job. Roll the window down and spray it into the weather striping on the front and back of the door not the rubber seal . Run the window up and down a few times and it should fix the problem.

BMW’s

Response:

I used silicone dielectric grease in the window channels only.  They slide like new, now.  Oh, I tested this on Fords, YMMV. PoD
