Are those glueless patches called Skabs or something like that? I see some type of glueless patch offered here called that, but I have no clue if its any good or not.

Here in Texas, especially in the over 100 degree (Farenheit, 40 degrees C for others) heat, a lot of glueless patch jobs just melt off, while the old glued with rubber cement patches stay on because of a stronger chemical bond.
