Same experience here.

Someone reported good results if the tube is cleaned with an
alcohol cleaning cloth first. It didn't work for me.

Has anyone used any that create a really good patch?

Not me, so far. In fact, I had better results with a piece
of carpet repair tape than with the self-stick patches;
long story, a case of "use what's at hand or carry the
bike home".

In a word: no.

One of myLBS won't sell them unless you ask specifically. My
personal experience is that even when you get a good bond,
the patch material fails after extended use. I don't have a
quantification of extended use; maybe it's many hundreds of
miles, maybe it's a few months. I learned my lesson before I
was able to determine the exact cause of failure.

Think of them as temporary get you home patches. I've used
them and never had one fail is as little time as your's
have. I followed the directions on the package, Park brand,
and scuffed up the area before applying. My patches were
lasting right around a year before they failled. I use them
as a backup to the extra tube I carry. That way if I get
more than one flat on a ride I have a way to get home.

Contrary to other posters here, I've had great success with
the Trek pre-glued patches, which I believe are the same
ones sold under the "Scabs" label, and possibly others as
well. I've found them permanent, providing they stay in the
tire (and it's kept inflated). The only time I've had an
issue with them is when I had one on a spare tube.

This has been my experience too. They work fine in the short
term, but always fail eventually. Sometimes it takes months,
but eventually you'll wind up with a slow leak. This is a
real pain when you have several patches on one tube, with
more than one leaking or about to leak. Finally, replacing
glueless patches with real ones is a pain, because it's hard
to get the adhesive off the tube. I've had my run with
glueless patches, and gone back to regular ones. At least
when I can...

The biggest problem with glued patches is that the glue
tends to harden once the tube is opened. Nothing's worse
than being stuck on the road with a useless, dried out tube
of glue. So I still carry a few glueless patches.

The glueless patches just don't stand up well under the
higher psi pressure of road tires. They work much more
reliably on my mountain bikes, however.

I would have to agree w/ the minority. I rarely have problems w/ park
glueless patches. I do clean the tire w/ an alcohol wipe prior to glueing to
assure a clean stick.

Glueless (or, as we call them, clueless) patches are a
temporary measure to get you home, not a permanent patch.
Once home, patch the tube with a real, glued, patch.

Carry only unopened tubes of glue. A 97 cent Bell patch kit
at Wal Mart, even if you don't like the patches, includes
the standard little tube of perfectly good glue; and for
home use, use the tubes you've opened on the road before, or
a jar of appropriate glue/Elmer's Rubber Cement/contact
cement (currently under discussion in rec.bicycles.misc, and
discussed in the past also).

I almost always run out of patches before using the whole
tube of glue. I put the remaining glue in the next patch kit
and keep using it with the new, unopened, glue as an
emergency spare. BTW, before I cap the glue tube I spread a
bit of glue around the threads to make the cap seal better.

I like that idea so much, I figured I'd quote it just to
bring some emphasis to it.

I've had that problem, too: two flats, dried out glue.

Since then I've operated on the theory that the air in the
tube of glue is what dries it out once it's been opened. So
now after patching, I squeeze the tube to remove the air,
then screw the cap back on. So far (ten years) it's worked.

Hmm... I don't have that problem...I think that the biggest
problem is that the tubes are so flimsy that they get a
pinhole and then the glue dries. I know I've had tubes dry
up that I've never-opened. I read here that that's what is
happening and that explanation jives with my experience.

I say you have to open up your patch kit once every so often
and verify by weight that there is still glue in there. As
long as you do so, you can carry partially used tubes.
