On my LS430, at the inside top of all 4 side windows is a black 1 1/2" composite seal (for lack of a better term) which helps keep the windows sealed when they are raised. Each time I detail this area, this "seal" is somewhat rough rather than smooth as it is after I've "dressed" it. I suspect this could become a source of wind noise in the future. How do any of y'all clean and/or dress or treat this area??
