The last plug I put in my rear tire was slowly losing pressure. I removed the plug and put another one in
with the same result. The air was escaping at the same point between the tire and plug each time (using the
soapy water test). I wondered if the reaming tool used to open the hole up, may leave some "jagged" bits of
rubber around the edges keeping the plug from getting a complete seal.
I removed the second plug and decided to test my theory. I used a blow torch to heat the pointed "probe" tool from the
kit, at the point where the taper ends. With the probe red hot, I inserted it into the hole for few
seconds and rolled the tool back and forth in between my thumb and index finger. The tire smoked and let off some
burnt rubber fumes.
I installed a new plug, aired the tire up to pressure and gave it the soap water test. No leak!
