Me too - I had a hell of a ride with two flats a broken spoke and a freewheel wedged chain - I have had off and on problems with Self adhesive patches but today I learned that even old not leaking self adhesive patches cannot hold up to 100+ degree weather - Two patches more or less melted off of the same tube on my ride today - Bastrop Tx temp was about 103+ but I am sure the asphalt was much hotter - For me its back to vulcanized patches only and a few self adhesive scabs as back up just in case my glue dries up...
