When it's spread on, yes, it's clear. It has a texture and color that is very similar to Vaseline.
Yes, and it's extremely effective. I changed the refrigerant in my truck to 134A and used it for all of the o-rings. I bought these rings over a year ago and have had no problems with them.
Yes, I used less than one tube to replace all of the door seals on a 2008 Uplander minivan. It should be applied thinly and thoroughly.
To the best of my knowledge, GM recommends this product for use on Corvette rubber seals. That is precisely why I purchased GM part 12345579. It's what I use on my C-. There are a lot of rubber seals on this 5 Corvette convertible.

On my 2015 GMC Sierra 2500, this is what I use. I recently purchased the vehicle and noticed that the inlaid door seals were squeaking slightly. While driving, use weatherstrips. I figure it's not a bad idea to keep some of this grease on hand to help lubricate and moisturize the strips. The squeaking has stopped, which helps to ensure that the weatherstrips are greased properly. When it comes to weatherstrips, remember that a little silicone grease goes a long way. It takes very little to keep them moist; just a dab will cover a large area of weatherstrip. This is something I recommend for all cars, not just GMs. As my weatherstrips wear out, it will be useful to have this tube on hand.
It really works. It applies smoothly to the rubber seals under the removable top of the C7 Corvette, as described in the owner's manual. I used a latex glove because it was less messy and easier to apply. It doesn't take much and the tube should last a long time.
It's a little pricey for dielectric silicone, but if you want genuine GM fluids for your car, this is the way to go. Surprisingly small, the tube was. According to my owner's manual, this should be used once a year on the door weather trim. It took the entire tube to finish all of the trim work on my truck.
I used it on the area outside of the car where I noticed cracking under the windshield wiper where the glass meets the car, and it was well worth the money. It now looks brand new, and we'll see if conditioning that area, as well as the door weather stripping, helps to prevent further cracking. It looks like it's made of the same stuff.
Works great on all of my vehicle's rubber door seals.
For my weather seals, I decided to be safe and purchase this expensive gm silicon grease. I want to make sure that my weather seals will last a long time.
The item I received is not the same as the one you described; it's from AC Delco, not the one in the picture.
