Rubber seals-303 aerospace protectant?

**CEE DOG** · 07-24-2009, 06:57 AM

Does anybody have any long term experience using this on the door and window seals, weatherstripping and the seals around headlights etc.???

What do you guys recommend?

Should I stick with the manufacturer recommendation?Weatherstrip Lubricant (GM Part No. U.S. 3634770) OR Dielectric Silicone Grease (GM Part No. U.S. 12345579)

If so where would I find this. I didn't have luck on the internet. Do I have to go to the dealer?

I have had great experience with it. It's all I use on my door seals etc.

I have used the 303 on my 04 Bonneville since purchased new and there is no wear on any seals. I usually apply after every other wash.

One disclaimer. I did pick up a container of Gummi Pflege and was happy with the results. I used the Plege on my 3 cars and my sisters car. I still continue to use the 303 but the Einszett product is a less costly alternative.

I like to use 303 Aerospace or Einszett Cockpit Premium. I've heard that Gummi Pflege is an excellent product for rubber seals but both 303 Aero and Cockpit Premium are safe to use on rubber and I always have those two products on my shelf anyways.

A next door neighbor of mine gave me a bottle of 303 Aerospace and it did one heck of a job. Since my car is all black, faded trim sticks out quite a bit after cleaning. So i found 303 to be great with really giving the seals back their color. SPF 40 in it too, which is great for black on black vehicle, because i usually roast like a country ham on hot days.

My only problem is, I can't smell. Therefor, I could not tell ya if it smells good or bad. LOL I do love how it seals all the wonderful black rubbers on the exterior of a vehicle. So far, I have not seens any runs since used.

Used to use it on my car all the time about 3 years ago. For some reason I just stopped. Well recently I've been on a "restore my interior" kick and noticed my seals are starting to crack and some pieces are missing. So it's time to bring them back and TR does the job amazing well. Also forgot how little you need, this stuff spread very very well.
