Today I bought some GM dielectric silicone grease from my local Chevy dealer for about $9.00 a tube, a small tube at that. It says on the blue and white tube model # 12345579. It's a clear vaseline looking substance. My chevy parts manager told me "most Corvette and Camaro owners use this stuff on their rubber weatherstripping around the t-tops, doors and stuff". He went on to tell me there's some "really expensive conditioning stuff" also. He said it's about $60.00 a tube and it's a conditioner for the seals but he says the dielectric grease would do "the same thing".
Tomorrow I'm gonna pick up an old piece of rubber seal from a junk yard and I will test it out. I will also test 303 aerospace protectant, Mothers blk to blk, Zaino Z-16 rubber and tire dressing and Meguiars' rubber and vinyl protecant.
Whatever product you decide use to do follow up with the 303 as a 100% UV inhibititor!
I want the damn truth on this grease stuff!
Somebody please explain to me how it's the BEST stuff on the planet to apply to your rubber seals/weatherstripping!
Thank you

The owners manual says to treat the rubber parts with silicone. Dielectric (non conducting) grease is for use one electrical connections that you want to isolate, like spark plug wire connections etc. and comes in that small tube because you're supposed to use just a little bit on electrical applications. Once you use silicone, I doubt that the other products will stick so you will probably need to use one or the other.

I used the GM product on the SS when it was new. I went over all the weather stripping and T top seals. That's all I've ever used on it.

Personally I would not use the dielectric grease on my weatherstrips due to the fact it does not dry and may make a nasty mess. There are plenty of products that can be used on the weatherstrips.I used dielectric grease mostly on the back of ignition modules and for wire connectors.

What others already said. I know a lot of Corvette and Camaro owners and non use dielectric grease for anything other than electrical connection and on the tips of plugs and coils or disty caps. Most of the times, when you buy new ignition wires, they give you a little with them
I use Zaino 3 or 4 times a year. The tire stuff. It keeps the rubbers soft and looking good!
No confusion except none of us seems to know where your dealer got that info about grease on rubber!
