General MotorsGenuine GM Fluid 12345579 Dielectric Silicone Grease - 1 oz.

Way, way expensive for the size of the tube. I was shocked when I saw how tiny the tube is. Likely won't buy this again. Will find another brand which isn't worth it's weight in gold.

Great for door seals

I use this on my 2015 GMC Sierra 2500. I just purchased the vehicle and noticed some slight squeeking on the inlaid door seals & weatherstrips while driving. I figure it can't hurt to keep some of this grease on the side to help moisturize and lubricate the strips. The squeeking has since gone away, and this helps ensure the weatherstrips are properly greased. Keep in mind a little bit of silicone grease goes a long way with weatherstrips. It does not take much to keep them moist. Just a dab of it can cover a good area of weatherstrip. I recommend this for all vehicles, not only GM vehicles. It will be nice to have this tube handy as my weatherstrips age over time.

this is one small bottle but it works really good on any kind of weather strip, i used to fix a leak on my upper window and it lubes really good and makes the window stick to the strip, i used half of the bottle for the passenger and driver doors and also for the convertible top and still have less than the bottle, like i said: its a really small bottle and it will last for the whole car if you apply gently with your finger

Little pricey for dielectric silicone but if you want genuine GM specific fluids for the vehicle, this is it. The tube was suprizingly small. My owners manual say to use this on the door weather trim once a year. Took the whole tube to do all the trim on my truck.
