CharlieRC, thanks for the tip. I will certainly try it once it stops raining here.

 

More on this is that the RC has frameless doors. Meaning that the window glass is the upper frame so to speak.
Therefore the window felt on the weatherstrip and the rubber is thicker material. As also you notice on frameless
window car the window moves that last bit to seal the windows. Another good thing about the weatherstrip being
more robust is for a better seal for wind noise. So, best to just slide a micro-fiber towel between the glass and seal
after a wash or excessive rain to dry it out. Hope this further helps those who think this weatherstripping is a defect.

 

That's the same on pretty much all cars. I've owned 19 cars of various brands and they literally all do that. Modern (that is any car after 1992) usually have a felt strip on the outside that basically holds water until it dries out. Any brand. Ford, Kia, Ferrari, Lexus, Honda, Daihatzu, Isuzu, Hyundai, Chevrolet, etc. Not a "Lexus thing" or "an RC thing"

you basically let it dry out in the sun after you wash your car and dont touch the window for a day or two.

 

I think its excessive too, I don't get the same lasting moisture in my wives RX (older one or current one) more any other cars I had in the past. I doubt there's anything wrong or that can be done to counteract it except for going the extra mile to soak up that water in the seals.

 

They've been putting felt in windows for probably 60 years now. It's just more prevalent on some
than others.
