Typically once a year I go around and regrease all of my door (and sometimes window) seals with Honda ShinEtsu Grease or Gummi Pflege (learned of it from BMW guys). I admit with two small kids I've neglected to do this on my Defender which just turned 2 years old a week or so ago. Nevertheless, I finally got to it this weekend.

I noticed that all my door seals have a ton of yellow on it. At first I thought it was just pollen. But its a TON and none of my other cars have this issue. I had to use 4 rags, one on each door to get it all off. Plus the Defender is parked inside like 90% of the time (I've only just hit 13k miles). Also the rear hatch seal didn't have it nearly as much. just the 4 seals on each of the main doors. It was yellow all around each seal, not just perhaps the top, or the forward facing portions of the seal. I'm thinking gravity helps collect it from the top but shouldn't be as bad towards the bottom of the door... but it was.


Is this some sort of coloring thats naturally emanating from the rubber seals itself? Or is it in fact just pollen. Curious if anyone else has noticed their seals turning yellow. As you can see from the towel it does come off relatively easily. But had me wondering if it was the seals themselves somehow failing.

 

Looks like normal pollen. Pretty common this time of year.
