Cheap patches and cheap self stick patches like the Scabs and other brands I can't recall now are junk, I only use Park glueless or Specialized Fatboy glueless which I think are relabeled Park patches, 3M use to make glueless patches but I haven't found those for a long time, but either of those 3 are the best glueless patches I've ever used and I've never had one fail...but preparation is the key for these to work well, and they don't work on latex tubes. Back in the day when I use to use glue on patches I only used Rema, but those days are gone and I'll never go back to glue on again. In my tubular days and when I used latex tubes I made my own patches out an of old latex tube and used Pastali rim glue to affix the patch to the tube, but there is a bit more to doing that then mentioned here.
