First off, wow. I should have used this the first time I replaced ALL of my weatherstripping.
Actually, while I was visiting my parents in Kansas I had it all replaced by the dealership...BIG MISTAKE!! I should have checked for their experience first :mad It was the absolute worst job imaginable. Besides leaking and tearing within a month (windshield/roof), the overall fit was horrible.
Anyway, I've had the actual windshield replaced (at the dealerships expense...different case) along with the weatherstripping. I bought a new top (old one warped). It came from the factory with weatherstripping.
On to the question:
Is there a better product to protect my investment than the silicon gel sold by GM?
I don't know if there is anything better. I've been using the GM product for a couple years. One tube is good for about 3 applications for me on all my weatherstrip. It's definately helped prevent deterioration. Also, it solved a minor water leak I had from the top/driver's side. I've been applying the stuff twice a year.
I actually use a product manufactured by BMW. It's called Gummi Phlege. Since this is not needed on a regular basis, I apply 303 Aerospace Protectant to it between applications of the Gummi Phlege. :yesnod:
You can get Dupont Krytox weatherstrip protector from Ecklers for $29.99... for a 2 ounce tube! They also have a less expensive alternative that is also supposed to work well for $12.99.
I've also used fluorinated grease available from most pool supply companies they use to lubricate o-rings and such. Seems to work but you need to use it sparingly. I'm sure the Krytox stuff is better but $$$.
I have a pool and bought a tube of Pool & Spa Lube from Leslie's Pool Supply for my pump o-rings, etc. WheN I saw on the label that it is "formulated with DuPont Krytox", I tried it on the WS. Works great, $4.99 for 3.5 oz (big tube). I have also used "Bulb Grease" silicon lube from Wal-Mart. $1.99 for a small tube, enough to do all of your weatherstrip.

Re: GM Silicon Weatherstrip Protector
I have been using the brand Standard SL-4 silicone dielectric compound on my car's for year's. It's the same stuff that you put on spark plug boot's. I guess if you go to a good auto part's store and ask for some dielectric grease that they will give you something similar. It look's kinda like Vasalene .Standard SL-4 is a-little tough to apply. But it's cheap and work's real good. A very thin coat lasts for year's. That's the hard part is to put it on real thin. Then go around and wipe any excess off. HTH
Ditto FrankUrbinati, found "STANDARD" brand SL-4 silicone dielectric compound at local auto parts store 1-1/4 ounce tube very thick, goes on easy and seems to stay. Apply sparingly should get 3 to 4 applications per tube.
Can't find receipt but seems like was around $16.00 for tube.
Has anyone ever tried a product called KryTech? The label states the following : " Wax Lubricant. Dupont Krytox Technology. Krytox wax technology. No greasy,oily film. Parts stay totally clean." Clear, liquid form. 2 oz. bottle. Purchased at a bicycle shop for $3.75. Manufactured by Finish Line Tech., Inc. Is this very similar to Krytox? What do you guys think?
I have been using the tube I bought from GM (silicon dielectric). However, I just noticed in the latest MAD catalog some weatherstrip silicone grease--three one-ounce tubes for $9.99 (Item #100-554). This is much less than what GM charges and I suppose the stuff is similar. I didn't even think about the stuff that Leslie's sells for O-rings, etc. but, come to think of it, the consistency is very similar to the GM stuff.
