I had to post this because I was very impressed by the results.
Someone posted in this thread earlier, a few pages back, about treating their door seals with some weirdly named stuff called Gummi Pflege Stift and I was intrigued. I have been dealing with some wind noise on my driver's side door seal for a while now and after seeing the price for replacement OE trim seals, I figured I give this a shot first. They seem to seal much better.
I also used it on my door pillars that were very badly oxidized after 20 years in the sun and I am amazed at the results, they look like new! I treated my windshield cowl as well, which was also very badly oxidized and again very expensive to replace.
I apologize for the terrible photos, I couldn't get great lighting in my garage.
Door pillars before, very oxidized and almost a matte finish after 20 years in the sun, but very hard to see in this photo...

Pillars after treating them (I needed to wipe the excess off, its on there a little thick). I made a red arrow to a spot that I missed so you can see how pale, matte and oxidized they were beforehand.

My windshield cowl with some of this stuff on it to show the difference.

So thank you internet stranger for this very weirdly named product suggestion!
