    Do any of you electron heads know of a "conductive paint" that could be used
    to make the rubber surface of a touch pad conductive again?

    In the mean time I will attempt to glue a small piece of Aluminum foil to the
    pad, and hopefully it will not "stick up" to the point of making contact with
    the grid all the time.....

    on the emergency side, you can buy paint for the rear window
    defroster at the autoparts store. I think it is pricey and it comes
    in tiny bottles.

    Not quite conductive paint, but might work for what you want:

    Liquid solder. Never used it, but others on the list report fixing PCBs with
    it.

    I got this ver fine brass mesh from Electronic Goldmine. It has a conductive
    adhesive on it. I use it to put togther broken solar panels without
    soldering. Works great for that, and I bet it would work nicely for a button
    too.

    How resistive is it, say ohms per inch? Is it used for repairing the heater
    element? Sounds like it could have some neato uses depending on the
    characteristic of it.

    Good question.....don't know the resistivity. I think we have the repair kit
    at my work, I will try to paint a sloth of known width and legnth and
    approximate thickness, then measure it. Yes it is used to repair the heating
    element.
    It is not too uncommon for one of the grid line to develop a crack or
    break......besides the repair kit the alternatives are do without that section
    working
    or replace the rear glass.

    Great, check it out and let us know. Wonder if I could use it to replace the
    resistors in a Marx generator. Must have some cool use!

    Caig Laboratories makes just what you need.
    It is called caikote and is a brush on conductive
    coating. The Pro Gold is great stuff too, use
    it all the time on connectors.
