I have half a dozen old patch kits lying around unused because the glue has all dried up or hardened. I was looking at the Park Superpatch recently at my LBS and wondering how others have faired with them.
Also for those who use vulcanizing patches- I learned years ago that after smearing the glue around the hole, light a match and set the glue on fire for about 5-10 seconds before putting it out and puttng the patch on. Does anyone else still do this? I just patched up my tube this way tonight and in thinking back, I have never had a patch fail using this method.
