For what it is worth, I recently discovered a wire (looks like a paper clip) clinging to my rear tire. When removing it I found it had the end embedded in the tire. After removing it I put some soapy solution on the tire to see if there was air leaking. Sure enough there was a puncture. i have Ride-On in the tire. I took the bike for a fast four mile ride on the near by Interstate returned to the house and checked the tiny hole again. No air bubbles. After returning home from a five day absence I checked the tire pressure and it was 42psi exactly what it was after the test ride. This gives me confidence the product works on minor punctures on the road surface of tires. Added benefit, no wheel weights.
