    Hello freinds of the Station Wagon,

    It's about all GM B-Body-Chassis, like '79 Bonneville, Caprice or Electra.
    I don't know, how it has to be called, so I just only can describe:

    After removing the Side-End-Moldings of the vehicle sky, there are rusty traces at the side carriers from central to the back, running down the D-pillar and had rusted the housing of the taillight.

    My questions are:
    How I should have to fix the leakage of the roof rack? I think, that the reason is a leakage through the mounting-screws. After removing the rack for painting the roof, there was black silicone between roof, plastic pads and standing feeds. But you will give me right, that this is not a thinkful sealing.

    If you have any idea, what I have to take as a long-termed seal, please tell me.

    (I'm sorry - to write in englisch is much heavier as I thought and in my mind you roll on the floor for laughing ;) )

    Best regards - Maik

    You're writing English a lot better than I could ever write German, even with a language dictionary.
    The leakage is likely because of a previous owner's incorrect sealing work. I would imagine there are recreational vehicle businesses where you live, correct? They should have a parts department, where you want to find a material that's a tight foam; the product I've used was grey in color. It will not only seal the rack, but the screws that hold it down.

    Two sided rubber tape.Find a width that is slightly wider than your rack.

    Hello Silverwinkiehobo,
    thank you for your kindly reply.
    Bit by bit the englisch-sentences of school came back in my mind, but it's really hard. And after 1h of writing and translating, my brain hurts like an old diesel-locomotive at startup...
    But it's ok - I will drive and restaurate my Catalina, so I have to lern a little bit more englisch (and something of your culture :D :D :D )

    "Recreational vehicle business"? Do you mean something like camping-workshops? If yes - no, there is no one next to me.
    But I had bought foam rubber with a one-sided tape from 2 to 4mms, for sealing the taillights in their housing. Screw the screws directly through this material may could seal it, or what do you think?
    Please, send me a link to the product you use. May I could find this or a similar in germany...


    Hello Peter,
    ok - but i think, that the rubber would tear during screwing in. Or is that, what it have to do? Clog the hole...


    Best regards - Maik

    there is a caulking which comes in a long string like thing. I believe the trade name slang is dum-dum grey in color about the thickness of a pencil and 12" long. it is sold in a box at auto paint supply stores

    Aaaah - Dum-Dum Sealing Putty or Buytl Sealing Rubber - I think, that my inner door parcels are mounted with this stuff - a thin but strong thread mounted inside for a better removability.
    I will look, how to get this as fast as possible.

    In germany it's called "Butyl Dichtband" - and so I had ordered this. 2 rolls of 7m Butyl-sealing-thread with a diameter of 6mm and1 roll with a 20m long Butyl-flat-sealing with a width of 50mms.
    Thank you very much for your kindly help ;)
