I have had my 06 MCSC a little over 39 months. He spends nights in the garage, weekdays in a sunny parking lot, and is washed every week or so with Meg's Gold Class car shampoo. I have put nothing on the molding in question. Has anyone else seen this kind of deterioration? The upper flange of rubber is about gone! This is the worst part, but it's cracked all the way around.
