Well I know from my 20year old BMW that seals shrink over time to the point of being useless. What should I use (since we know armor all if evil) to condition the plastic and rubber seals on my car?

 

303 Aerospace protectant. THE stuff to use. Tough to find (I had to order mine online), but it's worth it.

 

Rubber Seals:
The seals on most vehicles are no longer made of natural rubber; vehicle manufacturers use a specialized synthetic material called ethylene propylene diene monomer (EPDM).

Real rubber, or blends containing real rubber, just cannot endure the direct exposure to sunlight (ultraviolet light) and the harmful-to-rubber oxidizing gases in our atmosphere.

The soft seals around doors, windows, sunroof’s, hood and trunk are constantly being flexed and compressed all the while being subjected to a hostile environment. Use a product that contains glycerine (Iz enzett Gummi Pflege http://www.drivewerks.com or Zymol Seal http://www.zymol.com) a natural plant anti-oxidizing agent, it will prolong the useful life of the seal by restoring the original moisture and resist tearing and sticking

Alternative products- Wurth Rubber Care Gel Stick, is silicone-free, biodegradable, and water repellent. http://www.superiorcarcare.net

 

Thanks for the links i will look at those two.

 

Once again, TOWGT gets it. The product I recommended -- 303 Aerospace Protectant -- is specifically recommended for all the reasons he notes. I'm sure TOWGT's recommendations are also excellent.

 

Yeah I use PB's trim restorer and natrual look. I'm not locked into any one brand, more simply learning the limitations of a brand one brand at a time. I like the tech aspects of the 303 line. I will look into it shortly.
