Restoring Sun Damaged Rubber?

[Yelbom15]

I tried my best to get rid of what looks like fungus off the window seals. I’m located here in Florida and the sun ruins them.
Tried my best with a magic eraser to see if I could get rid of the top layer.
Any tips?

I heard somebody used Honda Shin-Etsu grease to hydrate and brighten up the rubber portions of this... I got some of that and have been meaning to apply it but I've used a toothbrush with bathroom cleaner first to prep it and have the same issue you have where those spots just don't want to disappear... so before I do apply that and try to brighten this up, I'd also love to know if anybody has a technique for at least removing these spots

Back to black type products help after a wash, at least for a while. Havent found anything that permanently addresses yet.

Have the same issue with my car, which came from FL. Been wondering if the solve is new quarter windows....

I’ve had some limited luck with 303 Aerospace protectant, but I’ve been meaning to try this stuff. Haven’t yet because it’s not particularly cheap:

Wash with Dawn dish soap, decontaminate (Iron X or similar), clay bar, 303 Aerospace Protectant. Or wash and do vinyl wrap.

we are talking about the rubber surrounding the quarter window - not sure how IronX plays into that??

I guess it's a habit of mine, I always use it an almost everything.

The for sure fire way I’ve seen so far is a high grit sand paper and whatever lubrication you choose…not sure how I feel about that. But I might chance it. Not sure on the longevity of the rubber after scoring it like that.

These trim pieces are lightly power coated. The only resolution to this is to remove them and have them recoated or simply mask off that area and repaint yourself. I've found that using a bed liner product would work also. Several other car guys have taken my advice and bed liner the door jams and roof top area that were suppose to be black powder coated but have faded as well.

An old tooth brush and some compound, suggested by the one and only Kevin Brown. Aka Buff Daddy.
