"and using Auto Silicone Sealer to stop your leak ? I just did this on my 80 240.... "

I have the same problem with my 77 240D, it is dripping in the trunk. I see two joints in the rear rubber seal, about a millimeter wide right above where it drips, I guess that I will try the Auto Silicone Sealer, lets see what happens.

Thanks,
