Bests & Worsts Reviews from Amazon

Instructions are pretty limited. Had to watch the Youtube video Park Tool made on this kit. 1) Clean inner tube very well using included sand paper or alcohol wipes then let dry. 2) Apply rubber cement to inner tube covering an area fairly larger than the patch itself. 3) Wait for the cement to dry. If you test for dryness do so outside the area where the patch goes. Your finger can mess up the adhesion. 4) Remove the foil side of the patch, leaving the clear plastic. 5) Apply the patch to the dry rubber cement area orange side down. 6) DO NOT inflate the tube outside of the tire. The patch will always end up blistering off the tube. It needs the support of the tire itself. 7) Leave the clear plastic, it'll protect the patch on the tube and reduce friction on the patch while you are inflating the tire.
