I still have a handful of those hot patches. The trade name is Match Patch. I quit using them years ago, as there is no need for them, that I can see. A properly applied glue-on patch is just as good as a hot patch. If the tube is not properly cleaned, a hot patch will not stick, any more than a glue-on will. These patches are 1 1/4" by 2", and a road bike tube is just over 3/4", so how would you apply a patch that is wider than the tube?
