The car is a 1979 300SD. The problem is the rear window is leaking. I purchased a new rear window seal but I am afraid to pull the window. If I find rust in there then what? Right now it looks like the window is glued in some how. There is rubber on the window side of the chrome (touching the glass) but there is no rubber on the metal side of the chrome (touching the body). I looked at a 126 body in my parking garage and it looks like the rubber seal is supposed to be on both sides. I don't have a 116 to look at and compare. I have heard from this board some people have sealed there windows with 3M 08606 Polysulfide Sealer. Does this stuff work? I would rather fix my car the right way but it is my daily driver and I drive to work everyday. If the decision is to pull the glass can anybody suggest a glass shop in the Tri State area. I live in New York City. Does pulling the window have any affect on the interior (headliner rear defrost etc...)??? Thanks all and applause to whoever started the thread about 116 ownership. It's about time we stepped up and made some noise!!! We can't let the 123 and 126 owners forget about us...
