I use liquid wrench brand spray silicone. I spray a little on a rag and rub it in. Then I do it again and leave a little excess on the rubber.

Interesting, I use soap and water.

Several people have said that the solvents in silicone spray can eventually damage the rubber. I would definitely do as you indicated- spray it on a rag so the solvent can evaporate, then rub it in.

Gummi Pflege is what most detailers swear by.

Thanks for the link. I already use 303, but I sent the link to some friends.

I have used silicone on all my cars for at least 30 yrs. and never a problem.

Thanks. I did not know this.

Leaving on a trip soon, so I swallowed hard and paid $75 at a dealer for the small bottle of 3634770. Next time I'll plan better and order from one of our Forum sponsors...

The liquid is clear and pretty thin, about like motor oil; not like any grease. On a hot day, excess can run down the weatherstrip and drip onto your interior.

Doing ALL the weatherstripping on the car used most of the bottle. It did NOT have any applicator.

I used a thin rubber glove on my right hand to apply it. The label has such severe cautions you'd think just touching the stuff will make your dick drop off, but I got some on my left hand and experienced no problems.

Our new 2009 was creaking and groaning like the old sailing ship in "Master and Commander" by the time it had 500 miles. It has the newest style top latches and I used the silicone grease on the appropriate points. A quick drive last night suggests the noise is mostly gone but not completely, remainder seems to be randomly located. Our 2006 had not a single squeek or rattle when sold at 44k miles, so I'm not entirely pleased with the sound effects of the new car.

Zymol it is greasy and attracts dirt. It comes from a plant.

This is a poly fluoride grease or oil (which ever one you buy). It and silicon oil are not very soluble in (hydrocarbon) rubber. The rubber in tires is "extended" with oils and that is why oils & grease (hydrocarbon based) will dissolve in the rubber weatherstriping and over soften it. The rubber in pencil erasers is very extended with junk too to soften it.
I used to use silicon grease in the midwest to stop the weatherstripping from freezing to the doors when the car had to be left out (at Purdue).

Low gloss, looks like new.

I talked with two dealers (including one I trust), and both said they use dielectric grease. Neither one has ever used the special GM weatherstrip liquid because it's so expensive.

The dielectric grease worked great for me. BTW, it seems a lot of people are only treating the weatherstripping on the body; make sure you do the seals on the removeable top too!

If you used most of the bottle, then you put way too much on.

I did my whole car and used about 1/8 of bottle, and only got a few places where it dripped.

Leave it on for 1 hour and then wipe rest off...and presto. It is expensive, but I figure I'll get about 8 uses from bottle that I paid $50 for.

It IS expensive, but also seems a lot less sticky than the dielectric grease I had used on our 2006. Several months after applying the grease to the weatherstripping on that car, I drove with the top off on a windy day in Florida. The weatherstripping looked like it had grown fuzz from all the dust that stuck to it. If I wiped most of the grease off after an hour or two after applying, then I needed to renew it more frequently.

I'll report back when I have more experience with the expensive stuff.

Great stuff!

This is non greasy which means that it doesn't make your weather striping a dust and dirt magnet. Easy to apply; it is in the same type of container as liquid shoe polish.

I ordered mine through AutoGeek.

I started using dielectric grease in 1998 on my Camaro SS after I read in my owner's manual. My weather striping still looks new and there has been no cracking. I have also began using it on my C6. It is messy as previously mentioned by another member, but its worth the mess.

You can use goose grease if you have access to a flock....what the flock? ...just kidding....
