    You're doing it wrong, then. Properly attached, a patch will not leak, and will last forever.

    Having taught many people how to patch rubber products -- just bike tubes, but all sorts of tubes, tires, and other equipment -- the biggest two problems are insufficient surface prep (no one sands long enough, it should take you 30 seconds or more to do the sanding) and improper glue application -- too much glue, not enough time waited for it to dry.

    A logical response. However, every tube I patched twenty years ago lasted "forever," and every tube I patch nowadays deflates overnight. I haven't been skimping on the quality of my patch kits or rushing the job. I just can't seem to get a patch to hold anymore. At this point, I've just been carrying two or three spare tubes everywhere I go.

    Found a second hole in the same tube. I have no idea what the boys ran into with these - both tubes had 2 holes. The other tube is in and patching this one.

    Oh, and using the shaving razor is nice to get rid of those little ridges on the tube plus featherd the cut patch. Wonder how well it will shave in the morning.

The far left tube I did 3 times because it deflated overnight ( haven't mounted these yet, just sitting on the table with a little air) until I found another tiny hole (middle patched section) and then a cut down Navarra path which turns out to be 20 mm dia.

    So an update - the far left tube, mounted in the tire, held pressure for the last couple weeks so I know it's good. Now the tube on the right is mounted last night and ... flat. I'll pull to see what happened.
