Tyvek race numbers work better and are cheaper and always around. I fold one up in my spare bag.

I doubt it'll help with a tubeless but I've patched a sliced clincher with the old folded up dollar bill trick. Saved me from an 8 mile walk home in the woods once.

The sealant just can't get at a hole near the side. I haven't been able to
get any sidewall cuts to seal up.

I just realized I hacked out some words on booting a tire.

The only non tubeless mountain tire I have had really good success with
(running tubeless on stans rims) is the "SCHWALBE" Little Albert. This is
29". I am sure there are other tires that would work as well or better than
L. Al, but they have been rock solid. They have a very sturdy sidewall. I
just mounted and raced Echo on stans rims..... the "HUTCHINSON" Toro
tubeless tire. NOW there is a tire that I think will live longer than I
will. These things have very strong sidewalls, look like they will clean
out mud very well (one of my main buying points of a tire as I do not change
tires for different surfaces) and I can tell you with a great sense of
security that these babies are sealed on those rims.... I only added the
sealant for a puncture. I know they weigh more than a tube-type tire, but I
think they will work great this season. I could tell you stories about what
I tried to do to get the bead to break free from rim. Of course if I do
ever flat, I probably will not be able to even get the tire off the rim. Oh
well...deal with that when IF it happens.(Book binding tape is also an
option for a damaged sidewall).

The internets report that glueless patches worked for some people.

For a small weight penalty this company makes a product that will seal
the entire inside of the tire, although I've heard it is vulnerable to
pinch flats at lower pressure: http://paradigmhosting.net/yes_tubes

I have used rubber cement common at any hardware store (forgot the brand
name) and a patch on the inside of the tire. It works great with the right
rubber cement. Tube patch glue does not hold well enough.

Hey all,

Is it considered safe to apply a patch to the inside of the tire? I have
heard that the glue from patches can attack the sidewall material. Is this
still true in 2010? What is the common practice?

I have not tried it with tubeless but I have with tires with large holes using tubes where the tube would have simply ballooned out and popped. My choice is Gaffers Tape. It is like duct tape on steroids and is used by photographers and studio grips. It is heat resistant, doesn't leave a sticky residue behind (that could potentially react with the sealant) and is very strong. You can find it at good pro photo shop or theater lighting supply place. It is not cheap, $25/roll but well worth it for more than just tires. I actually now have a 3-4inch piece stuck to the frame, bars or stem of all my bikes and has proven to be a great "tool" in times of despair many times.

Depending on the size of the hole, I've used super glue to seal up a hole that was just large enough for the sealant not to work. It's not going to fix a major hole or sidewall cut, and I doubt it would hold on the tread, but I've fixed up several tubeless tires with super glue.

Boot the tire. Glue on a patch or duct tape might even work. Go for
the patch first.

Mike,
The sealant will only seal small punctures. Larger holes and cuts just
aren't going to seal. You can try to patch it, but you are probably
going to need to get a new tire or run it with a tube.
Ii you need more advice the guys at cyclepath are the local tubeless pros.
Cheers,
Tony
