Rhino from Mysurvivalskills101?
I have had some rolls of gorrilla tape for 3+ years with no degradation. This was indoors however, so results may vary if you leave it in a shed or an open Jeep where it is semi/fully exposed to the elements. Gorrilla makes a great product though, this stuff is seriously tough, I am confident the tape would hold up pretty well in most any condition. Gets stiff in the cold and looser in the heat (like most things), but has yet to fail me.
