Anyone experienced this? After a nice drive today under the SoCal sun, I looked back (in cabin) and noticed grease/oil dripping and streaking down from the top. Hard to see it from the pic but is there circled. When I rub my hand over the top of the window (from cabin) where the rubber trim seal is, I can feel a thin layer of grease. Thought it was strange as it's just dripping down and leaving streaks on the glass panel.
