Glue on patches will last forever if done properly...I haven't tried self-adhesive patches so I don't know how good they are.

If I was going to use patches I'd go with glue on patches. But even with glue on patches the glue or whatever the more proper word is, will be dried up and useless by the time I ever flat. So I just change out the tube when on the road side. If I flatted a lot, I'd still change out the tube for new on the road side and fix the tube at home when I'm not in a hurry. But at one flat every two years, patches and replacing dried out glue seem to be more expense than a tube.

But I only came in here to see if the chemist has sung his praises for Rema patch kits yet.

That's pretty much what I did (before I went tubeless). I would swap for a fresh (or previously patched) tube and only carried adhesive patches in case I had a super unlucky ride with more than 2 flats. I would stockpile the punctured tubes until I had 6+ and then just patch them all at once, then rotate them into.

I've never used Rema. Though others sing it's praises. I wonder if Rema or some other has some little single use tubes. Then maybe I wouldn't be plagued with opened tubes that dry up before the second use.

Someone on this wonderful forum once told me that was because of not burnishing them properly, which is entirely possible because I only used that kind of tube out on the road. I burnished the next two tubes more carefully the next time, but went tubeless less than a year later and don't know how long those patches would have lasted. Lezyne brand fwiw.

Self sticky patches are great for a quick repair but for me, they don't seal that long. I've been using Rema vulcanize patches for 20 years or more with good results.
I do keep a spare tube of glue in my seat bag though, as they tend to dry out once opened and the patch won't stick without it. Hence why I carry Park self-sticky patches also. Overkill? Maybe, but I won't get stranded for a flat tire.
+1 for Urbanknight: As far as vulcanize patches, carry a small piece of emery cloth in your kit to sand the puncture area. If you don't sand the area, the patch won't stick well. It makes all the difference.

Lots of variables. I can report that Park Tool Pre-Glued Super Patch Kit GP2 patches seem well-suited to Pirelli TPU tubes...

Recently put tires on someone's bike and had to replace the stick on patch that was coming off with a glue on. Was holding air and probably would have held up inflated inside the tire but didn't like the tube being pulled out.

The OP should search the forum for my posts about rema.

My experience with glueless patches is mixed. It seems to me they have a tendency to lose adhesiveness over time, and once adhered and working, they eventually peel off. I usually have patched tube as my backup, do patching at home with Rema, IME, the best.

I've had a couple of stick-on patches fail after 5 years or more. If a glue-on patch is going to fail, it'll show up much quicker. Either will fail if you don't sand or grate the tube down before applying the patch.

The best patches were the old type which were vulcanized with a match or lighter. My grandfather used to help me patch tubes on my old Schwinn, and in the Southwest with its dirt roads and goat head stickers, this once at least a once-a-week task. The flames and black smoke were cool, the patches never leaked. But in a country with nearly 60% of the world’s lawyers, selling patches which require an open flame to vulcanize is not as easy as it once was.
Glue-on patches work well enough, self-adhering patches are hit-and-miss.

Rather than "glue-on," the term should be "cold-vulcanizing." The hot-vulcanizing process you describe was used before the chemistry of cold-vulcanizing was perfected. Hot vulcanizing is still used in industrial processes (like sealing the valve stem to the tube), but there's no compelling reason to use it in preference to cold-vulcanizing in repairing a simple puncture.

On the go I'll use self-adhesive, at home I use traditional vulcanized rubber patches, as they are the more durable of the two. But the little tube of rubber cement in portable kits, once opened will dry out quickly so they are less practical, and bigger.

losing track of how long I've been checking on these 2 glued patches, on my MTB. I see them twice a year when I do the winter tire changeover. I'll bet they are at least 5 years old
this one might be 6 or more years old

I carry a spare tube and a Park GP2 self-adhesive patch kit. I have actually gone through 3 patches on one tube on one ride - long story. I have an ever-increasing pile of tubes to patch, for which I'd use the glue on (cold vulcanized?) type of patches. But I had a bad experience with one a year or so ago, fortunately not on the road. A patched tube had held for hundreds of mile, and I was riding on the wheel-on trainer when suddenly my power and speed numbers went nuts in the middle of a race. Patch failed. Now I worry about that happening on the road, so I am hesitant to depend on patched tubes.
OTOH, I'm nearly through the 10-pack of tubes I bought last spring.....

Glue on only. Rema Tip Top brand only. Replace kit every couple of years if you don't get a lot of flats.
Sand well, put on glue
Be patient and let glue dry

Depends. Did anyone wave at you on your last ride? Did somebody spend too much on tech you don't find necessary? Did you control the lane? Do you use a bell? Does your bike have hookless rims? Is your chain waxed?
