Ive always used Silicone Spray to treat the weatherstripping in the back hatch to keep it from sticking. Based on feedback here i tried dielectric grease. Used it in a small spot first and it leaves a terrible greasey residue collecting dust and dirt. I tried to work it in the best i could. Am i doing somthing wrong?
A bottle will last your for years but the dispenser will kind of denigrate after a few uses. I covered it with some thin cloth from an old t-shirt and tied it on with a tie wrap and when that wares out I replace so the original top still works. Other than that, this is the only stuff to use. No mess, no sticky residue. Once a year is all that is needed.
I tried a type of grease like you and had the same results. So 99% of the time I use silicone spray. I have also used a spray dry lube which seems to work pretty well.
Why would you use dielectric grease? I agree with others, silicone if you’re old school or one of the new rubber conditioning products.
Maybe because that's what GM tells you to use?
P. 299 in the Owner Manual for our 2017
GM also makes a special weatherstrip lube, I'm surprised they didn't recommend that. But it's hugely expensive and seems to evaporate and leave a film inside the windows, even if wiped down after application.
The dielectric silicone grease is tolerable if you apply out in the sun on a warm day, rub it in, and then wipe off as much as possible.

ah, dielectric SILICONE grease. Did not know that. Thanks
I've been using dielectric grease mainly because the manual specifies it and I had a tube lying around. I've had no dust or other issues although the grease is, well, greasy if you use too much. I apply it, then wipe most of it off with a cloth leaving only a thin film. I think any preservative recommended for plastic and rubber--e.g., Armor-All, 303, Lexol Vinylex, etc.--would work fine. I used Armor-All on my C2 for 32 years on the seals, vinyl seats, dash, etc. and never had a problem. I applied, let dry for a short time, then wiped off
I have used GM Super Lube® with PTFE, P/N 12371287 (in Canada, P/N 10953437) in several previous C6s and my C7 for the "snap/crackle/pop" issue. Worked for me overall quite well....always have a tube in the hatch.

At one point, the GM bulletin about fixing squeaky targa tops said to use Superlube paste on the weatherstrip (and some other parts). A later version of the bulletin said not to use the Superlube, I think they went back to dielectric silicone grease but not sure.
When the Superlube recommendation was in effect, I cleaned my C6 weatherstrip and applied Superlube. A year later, it had turned into a gummy gooey squeaking creaking mess. It took most of an afternoon to clean it off and go back to the dielectric silicone grease. Others had the same bad results, but obviously not you.
