I have just acquired a 1990 300sl 24v with 46,000 miles on, rain gets in through the corner where the roof (both hard and soft) m eets winscreen frame and door glass.

I assume the problem is with the rubber seal,

Has anybody had any experience with rain ingress, and any practical solutions ?

The knock-on effect of this problem is that water is dripping in, and collecting under seat, and coming into contact with electric seat relay control unit, thus corroding unit to a stage where seat movement is intermittent

answers on a postcard please !
