The users manual says to maintain your weatherstrips that you should use Weatherstrip Lubricant (GM Part #3634770) or Dielectric Silicone Grease (GM Part #12345579). I have heard that silicone should not be used on weatherstripping. The GM Lubricant is very-very expensive. What is the best to use? I see that others have suggested using 1Z Einszett Rubber Care Stick Gummi Pflege. Are there other sources/items that can be used. What has been your experience.
Some folks will use 303 protectant on these as it gives fabulous UV protection and will help keep the rubber supple.
ABSOLUTELY AGREE! Much cheaper per oz. than Gummi. Much more versatile too. Great for interior too. I spray directly on a microfiber glove and use fingers to apply to weather stripping. also extends wiper life and keeps plastic and vinyl looking new for years. A must for any detailers arsenal IMO.
