Puncture Repair is a Myth

Its very Possible.. Im a heavy fucker and my repairs do do better than the tube. Apply a fair bit of pressure to the patch once on the tube and push from the middle outwards. The crayon is there as a snack while you wait or you could use it to mark the puncture on your tube.

good luck...

i thought the chalk was both a marker and for making dust to neutralise excess glue after the patch has been stuck on? does yellow wax even make a mark on the black rubber?
