Query: Great patch kit if you take time to patch it right.

I'm replacing my old Park Tool patch kit. I've had these patches last for years on mountain bike tubes. Never any problems. The tubes wore out before the patches did in many cases.My advice is to use only a pea size amount of the glue after scuffing the tube then spread it around to the size of the patch (it will dry better this way) and let it dry to a very tacky feel. Place the patch over the glue and stand on the patched portion of the tube for a couple minutes if you can. Insert tube into tire making sure not to pinch the tube under the bead of the tire. Voila! Great patch kit. Thanks.SPO
