Hi all I was about to tackle the mountains of doubleveiw on the niner 
when phhhssst spraying all the gunk out unable to get the valve out for a Quick rode side fix & throw a tube in I limped home two cartiges later tyre off rim I've found the hole in the tyre that wouldn't seal. I'm going to patch it see how it holds using tube glue & patches my Q. Is there tubless tyre SPECIFIC patches available..in my haste to get home taking short cuts I managed to run over a can of paint that some b-rsted had poured out on to the grass but I'll tackle that with the servos high pressure water cannon...cheers all

One of my mates was saying yesterday that he keeps 2 CO2 canisters and a tube of superglue for those big tears in the tire sidewall that Stans goo won't seal. I'm gonna buy myself some quality glue tonight from Bunnings for the 6 hr race.
Not sure about tubeless tyre specific patches, but I recently had a normal vulcanized tube patch which had stayed adhered perfectly to the side wall get pushed out through the small cut in the tyre by air pressure and then burst. So the thicker the patch the better. The cut still held air with sealant before the patch so it was not big at all.
Velox make a tubeless specific tyre patch kit - http://www.chainreactioncycles.com/Models.aspx?M... which includes a couple of small patches for pinholes, and a larger one for tears.
I've used one to good effect on a Maxxis LUST tyre that ordinary patches just wouldn't stick to.
A mate a mine swears by glitter/ stans mix ... makes the sealant tackier and thicker .... also makes the room spakle when a tyre exploded one night in the tropics
I've always said that with a decent MTB tire (Maxxis LUST works for me), punctures and sidewall tears will be extremely rare.
I run UST, and apart from a spare tube, hand pump etc, I also have a Park Tools Tire Boot. Basically a big, thick patch made for sidewall tears. It's pre-glued and goes on the inside of the tire (obviously). Not sure exactly how well it seals, but I'd also be using a tube in the situation. The patch might not be air tight, but it would be good enough to prevent the tube from bulging through.
Ps. I don't use any sealant either.
I bought a canvas tent repair kit from the Army disposals.
These have thick strips of adhesive canvas. In the situation of a big tyre tear you stick them on the inside, bang a tube in, inflate and carry on. Best 2 bucks ever.
Some people say to use a 10 or 20 dollar note as an emergency patch, but I cant get the bastard to stay put while I get the tyre on and inflated.
pre cut 40 x 100 milk bottle plastic. totally free and weighs nothing
I thought that 's more a case of when you rip your sidewall to shreds. yopu then insert a tube but place the $5,$10,$20 note where its ripped but it stops the tube from popping through the rip.
Yeh that's right. The problem is that the note moves during the tube insertion, tyre reseating and inflation process.
I use the canvas stickers cause you stick them over the hole so it won't move.
As you say all it does is stop the tube popping through so you can get outta there. Not meant to be a long term repair.
ohhhh..... Right you are
If you are in trouble and need a quick fix to a sidewall you can rip a small area of newspaper or catalog and put that on the inside of the sidewall before inserting a tube and inflating. Works the same as the $ note but if the paper is wet it also moulds easily. I have used this method and it got me home and you often find newspaper etc. by the side of roads.
These are all great tips but if you can't remove the valve ya stll up a creek in a fly wire boat with a broken padel headin for a water fall.....
