Unhappy Badly leaking hardtop

I am new to the forum and if you guys are anything like the crowd on mbcoupes SEC forum then all my problems are solved!
I am the proud new owner of a 94 SL280 which has led a charmed life in a garage, is in immaculate condition and I love it. The seller put the hardtop on for me to drive it home and 2 days later the heavens opened and most of it came in to my SL. The leaks are both sides at the point where the hardtop meets the top of the screen and drips inside the windows onto both seats. With the ammount of water coming in I would expect to see evidence of water damage to the interior but there is none (charmed life I suppose). This is really bad. Is it a common occurrence? Will removing and refitting help, is there a gook I can squeeze in which can be wiped off next summer? I have to get this sorted now or my car will be wrecked. Any help gratefully received.

similar problem

I had a similar problem with my recently purchased 380 SL.
I had the window resealed and it solved the problem. They just ran a silicone sealer around the window edge ($35). I had water dripping from the interior lights and the rearview mirror! It corrected that problem....but I still have water in the rear floor when it rains. I think theres rust holes inside the hood air vents causing that.

leaking hardtop

I had the hardtop off today and it looks to me like the front seal isn't doing the job properly, perhaps it became distorted in storage. to stop any water ingress here I have simply run a length of electrical black tape over the join (you can't tell it's there. I also put some silicone grease on the rubber seals where they meet at the edge by the windows. Of course it has stopped raining now so I can't tell if I have fixed the problem. Will report when the heavens next open- won't be long, I live in England!

Numerous seal changes and other tricks

There are a number of threads on this. Searching for "leak" in the SL forum may be enough.

I used to have a few drips on one side, at the front. Here is what I learned:

- There have been numerous changes to the seals over the years to solve leak issues. My 1990 SL had none of the changes. If the whole lot need replacement, it is expensive, as it involves removing the windshield. The Alldata CD contains comprehensive, but somewhat incomprehensible instructions on changing the seals. I did not change any of them.

- Using an air hose to blow out the two drainage channels that are in the windscreen pillars has been enough to fix leaks for some people. I did that at the same time as the fix below, so I don't know whch really solved the problem.

- In my final two winters, just having a film of vaseline in the joint was enough. I saw no leaks at all. (I only drove 5k miles per year total with the SL, so I may just have been lucky.)

- I never had a soft top leak, even in very heavy summer storms. So it is not inevitable.

dripping on knees

Is there an easy way to remove the two air vent grills on the hood?
I think I have some rust in there. When it rains, I get drips from under the steering wheel. I think (and my mechanic) thinks theres rust there finding its way under the wheel and somehow, to the rear driver side floor also!

Oh the infamous 'A-Pillar' leak

129's are extremely prone to water leaks at the top outside corners on the front (the A pillar) There was a service bulletin with modified seals and gaskets in a lame attempt to fix them.

On my 94 sl, I lifted up the windshield top gasket (removed the end plates) and added a wedge of RTV to raise that A pillar cap seal. That nearly stopped the leaks (they DID pour in). Then a good slathering of silicone GREASE along the rearmost grove al across the top did the rest. Be careful not to plug the tiny drain holes on the ends that allow water to drain down the windshield edge. One big fault in the design is the drain channel HAS TO BE SEALED all the way to the bottom of the windshield because the space between the outside windshield edge trim and the windshield is a HIGH PRESSURE AREA when moving. Any leakage of air into the water drain channel along the edge of the windshield will cause water back-up and probable leakage into the low pressure inside of the car. Engineered like no other car.

$15K Japanese toyboxes with cheap ragtops don't leak. My 1964 Chevy Impala SS 2 dr convertible (red/white POWER top, cherry leather interior,A/C, Hiperf 327, AC, etc--)would now be worth lots more than my 94 sl-600--and my brother and I replaced the top in an afternoon--and it never leaked a drop--even in South Louisiana thunderstorms and hurricanes. Sorry I sold it--but got drafted in the Army and it needed main and rod bearings.
