    Just on the nipple, 3 layers seems to do the job. Some of the nipples
    will need a wee bit more as you"ll see upon final inspection.

    I let it cure for 12 hours and put one layer on. Mounted the tire and it holds air. Lets see how it looks tomorrow...
    So did someone do the front on an Adventure too?

    Getting ready to do my rear rim on a 950. When you say just do the spoke do you do around the nipply also,and what about the valve stem, is an automotive stem that is used...

    I did each spoke nipple with a glob of Goop, did 3 spokes at a time and let dry for about 20-30 minutes. I placed my wheel on a truing stand. I covered the spoke and the valley or indentation around the spoke, the Goop will flatten out as it dries. I did each spoke twice. When I put on the tire I had 2 that leaked. Had to redo them. I did my front wheel also, but inflating the front wheel and getting it to seat on the rim was next to impossible. The rear inflated no ptoblem at all. I have had one flat on the front, just pluged it, still going strong. Good luck.

    I'd be tempted to add a strip of Christy's 10mil or 20 mil thick plumbing tape as rim tape too...That stuff is good.

    Also a bit concerned about reseating the bead to the rim if a tire goes flat out in the boonies and I don't have a compressor to help with the volume. Suppose you could always throw in a tube if nothing else works.

    How is it any easier to seat the bead if the tire has a tube in it?

    Also, in my experience, even a tire with low pressure (25-ish) that does not have the bead seated will seat it on its own once you ride the bike. I think it is a combination of a little centrifugal force and putting heat into the tire but they always seat on their own for me.

    Here I go. Needed a new back tire any way, so lets give tubeless a go. This is precleaning.

    You nailed it. That's the way to do it, except it's best to go all around, doing 1/3rd
    at a time to give the Goop a chance to set, then let it sit overnight between each of
    two more applications, still doing 1/3 at a time.

    Difficult beads can be seated by using Murphy's Oil Soap (veggie based,
    so won't hurt rubber), and warming the tire can help a great deal... Setting
    new tires in the sun in summer or in the house in winter can make a big
    difference. For really stubborn beads, I use a blaster, like this:

    Vegetable oil certainly will damage most rubbers. I wouldn't use anything vegetable oil based on my tires. windex or dishsoap (1:2 with water) works just fine for tires.

    Wow, you are out of touch. Murphy's has been used as
    tire mounting lube for many years. You can catch up here:

    It may be that murphy's is fine as a tire mounting lube, but it's not true that vegetable oil based things are not harmful to rubber.

    Edit: and second of all, the link you posted doesn't say anything about using murphy's oil soap for mounting tires. It's a link to murphy's tire mounting compound, and the companies have been separate since 1991.

    Says right here that the "Murphy's Original Tire Mounting Compound"
    is "Thick vegetable based, jelly-like lubricant"
    http://jtmproductsinc.net/murphys_tire_tube_mounting.html

    I mount tires almost every day (3 today), and it's Murphy's every time,
    for over 15 years. The tires are happy with it, and so am I.

    I'm sure they are, it looks like good stuff. I saw the words vegetable, oil, and rubber and reacted to that. murphy's oil soap for tire mounting is a new one to me, but I only do my own tires, maybe 1/2 dozen a year, and dish soap works well enough for that.
