I have had 100% success with both Park glueless and Schwalbe glueless patch kits. I use alcohol to clean the tube and then put the patch on and put the tube on a hard surface and roll a socket over the patch. this patch has about 6000 miles but the last puncture is too big to try. I carry a patch kit but also carry spare tubes. I have had no issue patching aerothan tpu tubes.
