    I used ELECTRICAL TAPE in place of real rim tape on my Coker. Also used
    a WTB 29-inch tube. Both worked well for over a year with no flats.
    But yesterday, flat as a pancake.

    Pulling it apart I found curious parallel rust colored lines on the
    inside of the tube and could find no obvious puncture. Under water I
    located the hole, very tiny, right on one of the rust colored lines. I
    inspected further and found the rusty lines have a scratchy feeling
    residue, kindof abrasive and sharp. Hmm.

    Bike shop friend concurred that rusty lines could be a combo of the
    ELEC TAPE ADHESIVE AND RUST, and that the tiny hole might be a result
    of the abrasive deposits.

    Anyone have this experience?

    Maybe this is ANOTHER REASON NOT TO USE ELECTRICAL TAPE.

    USE RIM TAPE MADE FOR THE JOB.

    What do you think?

    I don't know the chemical constituents of electrical tape adhesive, and
    whether it might have reacted somehow with the rim you were using, or
    if the adhesive edges of the tape just picked up particles that built
    up into abrasive, saw-like lines. I've used electrical tape as an
    addition to rim tape on my LM rim since I didn't have super-wide tape
    like you can get now.

    What rim were you using, the original or an airfoil? I'd assume not an
    airfoil, as that is aluminium, and will not rust into sharp particles
    like you describe.

    Loose.

    My Coker is stock with steel rim. Haven't determined yet if the rim is
    the source of the rust. The other possibility might be that the wire
    bead on the Coker tire could be exposed and rusting.

    Loose, you hit it just right with your term, "saw-like lines."

    I'll check it out further and report if I can determine what's
    happened.

    By the way, John Childs, you've recommended many times not to use
    electrical tape. Guess I shoulda listened.

    Not many times. I did get curious enough to try it recently in my
    Airfoil rim and found that it didn't stay put or in place well enough
    for my liking. I put it on and took it off the same day.

    The rust could be from the rim. The bead hook on the rim kind of curls
    around and is an area that condensation could get to and cause rust in
    the rim. If the rust is from the rim then the type of rim tape isn't
    going to make much of a difference.

    I'm also a fan of using talc baby powder or climbing chalk to coat the
    inside of the tire and the tube. That keeps the tube from sticking to
    the inside of the tire and seems to help reduce some types of flats due
    to pinching.

    Spend the $1-$3 on real rim tape or a rim strip at your LBS. It's just
    better that way.

    I used a length of Coker rim tape to insulate a 240V wire exposed during
    electrical work at my house. However, the wire poked through that
    little hole for the valve and electrocuted the postman, tripping the
    switch and plunging the entire street into darkness in the middle of
    East Enders.

    It seems that each tape may have a distinct purpose for which it is
    optimised.🙄

    Coker rim inside surface was rusting significantly, which is wierd
    because I don't ever recall getting the wheel wet. My guess is
    condensation like JC mentioned. I believe the rust did cause my flat,
    based on the size and location of the puncture.

    After inspection, I don't think the electrical tape contributed to any
    problem, including rust and puncture. It wasn't even a gooey mess.

    Nevertheless, I removed the rubber rim strip and elec tape. Brushed
    out as much rust as I could. Got the rim trued by the LBS, had them
    use rim tape this time, and even had the LBS put it all back together
    including a new 29-inch tube. Cost me a few bucks but they did a great
    job.

    I'm back happily rolling on my Coker. But I am still excited for my
    LiveWire 36, that is if it ever arrives.
