i carry 2 tubes and a pump, i still want a backup
carrying 2 tubes means i will try patching -> almost never
which means if i have a regular glue patch kit, the glue will INEVITABLY be dried up
(even if i never opened the tube)
if i don;t want to bother with buying new glue every year, and wanted to try glueless as a last resort, what are the current best ones?
(since they need to last practically forever, i am also not interested in glueless patches whose adhesive becomes invalid in a year or two, either)
