I know this has been brought up before but has anyone actually used the stuff? I carry a homemade first aid kit in my backpack when I ride my Shadow or when I'm popping cans in the woods. I'd like to know its limitations like what to not put it on. I hate being sewn up even when the adrenaline's still in my head. Let me know what y'all think. Oh, & don't get stabbed.... It sucks.
