My 97 GLE is already starting to show signs of oxidation building up around the rubber molding around the windows. It only has 31K miles on it! Why so early? Anyone out there experiencing the same thing? If so, what products can you use either to remove it, treat it, or just masquerade it?

 

If it's been parked outside since '97 and been battered by the sun, milage is not a factor.

 

is going to definetely be a factor. I noticed in some of my rubber strips it shows early signs of oxidation also. well, I live in NYC and the air isn't exactly the best. I do wash my car, and in the rubber area I do put some wax on it to prevent it--possibly?
I heard that silicon spray can help protect plastic as well...I am not sure about that--any one know anything about this?

 

Fortunately my 96 is holding up except for the black plastic pieces on the doors next to the windows. I just took some rubbing compound to that and made them smooth. It doesn't look glossy black - just a flat black. But at least it looks more uniform. Plus its way easier than painting them. Where do you live cuz that may have a bearing to your prob as well (is the sun "hotter in some regions?).

 

Rubber and waxes don't go together very well. The petroleum in the waxes actually increase the fade in the rubber trim. I don't recommend the use of any wax or silicone protectant that is petroleum based for the rubber or plastic especially if it sits out in the sun all the time.
