Zero patches for this tube. I had a slow pinhole leak that would take a couple days to notice. Put the tube underwater, found the leak, roughed up the area, and put on some glue. Before putting the patch on, I wanted to confirm the exact spot where the hole was, so I put some air in the tube (maybe 10 lbs) and looked for the telltale bubble in the glue.
Could not find the bubble, so I rubbed fresh some glue over the old glue, and BAM! the tube explodes. Never seen that one before.
