In the year that I've had my 82 380sl, I have been frustrated with water dripping into the car from the top seal area even while just washing the car. THinking it was my softtop seal, i reinstalled the hardtop, with no improvement. Talking to other sl owners, they have the same problem. Well, the problem is NOT the top seals, it IS the sealer mercedes originally installed the windshields with. After nearly 30 years, it has crumbled and cracked under the stainless trim. I had a new window installed at a local autoglass repair and NO MORE LEAKS, even in heavy weather. The BEST $265 investment i have ever made.
