    Default sunroof leak stopped by soldering

    the sunroof cassette, done by my backyard hack mechanic buddy TAKE on his 750

    Apparently not all water drained the intended way thru the drain holes, but it came out of the cassette frame and dropped onto the headliner.

    Well, the soldering is not that neat and smooth, as we are not soldering experts.
    But the main purpose was to seal the leaks, and that was successful.
    Took the same soldering iron we usually use for soldering LKM etc

    I found on Harborfreight a
    COLD HEAT CORDLESS SOLDERING IRON
    Advanced technology lets the soldering tip heat and cool instantly for safer,more efficient metal bonding. Ideal for light-duty or occasional automotive and electronic soldering, jewelry, crafts.
    No cord! Super-efficient design uses four AA alkaline batteries (not included)
    Reaches 800° F in 0-1 second, cools to room temperature in 2 seconds or less
    Built-in LED work light
    Ergonomic design fits right or left hand
    Replaceable tip
    ITEM 91298-6VGA
    regular price $19.99 discount price $12.99

    Wonder if I should buy this one, especially for soldering electronics.
    Anyone uses somehting like that?

    Maybe a new gasket would prevent the leaking in the first place? I have to get one of those.

    Usually yes, Kriss
    we did that also, but did not help in our case.
    As usual, start with the simplest and lowest cost version of repair.
    If that does not help. go to step 2.
    Bruno's website has the gasket replacement info.

    Did he build up the edge with the solder to contact the gasket? I can't tell from the photos what happened here. Am I missing something?

    i haven't used one but i have a buddy that has and the verdict is it's ****, absolute crap, how it works is a pair of electrodes on the end short out on what you are soldering and that's where the heat comes from, brian said he tried for 10 minutes and made one bad solder joint, and i know he knows how to solder, ymmv

    Thanks, so the top skin had seperated then. Simpler to replace the panel, no? Still a resourceful remedy.
