In the last few weeks, both of my Boxsters have exhibited the exterior rubber trim folding in when I put the windows down. It is worse in the 1998 than the 2000 but they're both doing it.
I have clayed and cleaned the windows inside and out.
What can I treat the rubber with as a lubricant that will not leave leave the windows in a mess every time I put them down?
