Electrically conductive paint?

    Bad idea . . . remote is taking more pressure this morning, so if it
    is migrating through the membrane it is filling the membrane so my
    experiment won't prove anything.

    But that suggests a second experiment: soaking the keypad in hot dish
    detergent over night.

    I don't have any. Most of the aquadag I've seen is fairly brittle and
    not very flexible.

    Do you use the liquid?

    A few times i have taken a small piece of wire bent it like a very small
    staple and pushed it into the rubber over the worn pad .

    i find that the repair kit sold in many places to fix the
    heater tape connections on your defroster work well.
    an applicable conductive brush on that is highly conductive with
    most likely copper in it..
    dries in a short time.

    If you have some Sheffield "Metalic Leaf Finish" around, either the
    gold or silver, it is conductive. It costs about $7 for a 55 ml jar.
    You can find it in most paint or hardware stores, etc. Some Testors
    paints are also conductive, i.e. chrome IIRC.

  6. I wonder if the stuff to repair rear window defogger strips will work
    for this? Has anyone tried that? Can you still get it?

    I use a German product called 'Leitsilber' , silver conductive paint,
    bought in electronics suppliers. pricey but has done many a remote for
    me.

    I don't know if it's come up yet but GC has a product called "Nickel
    Print" that you can pick up at electrical/electronic supply stores or
    order online. I've also heard good things about the very expensive
    rubber keypad repair kit.

    Yo CRaSH... waddya drinkin' them Old Fashions with a cherry again?

    What are you doing over here?... Never mind, it's completely logical given
    your test bench.

    Hey, this is a fascinating group... I'm glad I found my way here, I've
    already found all kinds of interesting little tidbits in other threads. In
    case you didn't know, in my neighborhood I'm known as the guy who can fix
    stuff that every other repair guy considers hopeless.

    Update on my repair adventures today:

    First this is not a remote control, it's a $ 1200.00 medical device I'm
    fixing for my neighbor. They won't send you a keypad because they don't do
    parts. Accessing the keypad takes about 7 screws and 3 minutes. They want
    the patient to rent one and send the broken unit to them to fix for hundreds
    of dollars. Bastards.

    The first attempt was using the Window Defogger repair paint. I could not
    get the silver paint that I've heard about, instead Permatex sells a new kit
    called "Complete Rear Window Defogger Repair Kit". Long story short, that
    paint actually flaked off the surface with no effort.

    Next, I tried to stick a tab of adhesive aluminum duct tape to the pad but
    the area is too small to hold the tape. Next I tried to glue the piece of
    aluminum duct tape with E6000. No way... pops right off the surface.

    Then I tried aluminum duct tape using super glue and it adhered nicely. I
    think the key here is that the vinyl pad won't hold paint or contact
    cements, they peel right off. I think the solvent in the super glue etches
    the vinyl and makes a very nice adhesion. So far so good.

    I'm guessing the aluminum duct tape is a better choice than aluminum foil
    because of its increased thickness.

    Anyway, God Bless Usenet, I can't even remember how many times it's provided
    answers that would have been impossible to get before the Internet.

    Thanks

    Hey Edd, I'm going to need to have a backup on this repair in case it goes
    south. Is the material Ken Weitzel referenced the same material you're
    talking about?

    Have you tried my pad substitution method detailed some distance further up
    the thread ? Works well for me ...

    I was strongly considering it especially since I've got half a dozen old
    dead remotes in the attic I could scavenge. But, I was afraid that the
    super glue wouldn't adhere the two and I would be left with a shorter keypad
    pad. But, now I know that super glue does work so if I have to redo it will
    be high on my list of options.
