Quite a few years ago I tried some glueless patches for repairing my punctured tubes while out on the road, and found that they rarely stayed on for very long. I know that technology has advanced a lot since then, and I am wondering if I should now try them again? Do they work?
Slime scabs suck as a permanent repair. I think they would be fine for a temporary repair, because that is about how long they last. Self vulcanizing cement and regular patches are still the best way to go. I still have some scabs, but will only use them in an emergency, or when I patch my ex girlfriends tubes.
I have used the stick on patches. The durability is conditional with proper installation. 1-scuff the tube 2-try and have the tube the same size as the inside of the tire. 3-after placing the patch on the tube take a smooth object and rub air out from under the patch. This is the most important step!
Glueless patches are to get you home, and glued patches are for the permanent repair once you make it home.
Personally, I carry a spare tube and glueless patches, and at home I have a nice glue kit. The glue kits actually bind the patch to the intertube, where the glueless stick on top over the puncture. That being said, I've had glueless patches stay on until I tossed the tube.
No! Still the same experience as a few years ago. Don't bother wasting your money on them (again). My experience has been that sometimes they don't even get you home before needint to be reapplied. Carry a spare tube and if you get a flat, take it home with you and patch it with a glue patch, or carry one of the small glue patch kits with you if you are flat prone.
I've had no problems with the Park ones that I haven't had with 'proper' ones and haven't felt the need to replace them when I get in. Like regular ones, my experience is that if it's on, it's on and if it's still good after 24 hours then it'll last as long as the tube. I've had some issues with getting them to stick in the rain but I think that probably applies to all patches.
I use the Park GP-2 patch kit and have found them extremely durable, lasting the lifetime of the tube. This is with 28-32mm tires and pressures up to 90 PSI or so.
