I tend to try and take things that will stop you, and vehicle specific stuff too..
but i think you covered most of the general stuff, except i have a new essential Rescue Tape, that stuff is awesome you get it at boat shops it goes for 15bucks a roll, and is a silicone based tape that seals just about anything.. i made a diesel return line outta it and it got me home from newcastle..
is that that Tommy tape stuff they have mentioned on 4wd action Trav? I think Roothy used it once to repair a blown radiator hose. He just wrapped it around the spot in the hose where the pin hole leak had developed and it sealed fine.
