can this (or any other sigg for that matter)...
can this (or any other sigg for that matter) be used as a fuel bottle for my whisperlite?? or just storage for fuel??
You might be able to but I wouldn't recommend it. The fuel is pretty corrosive and other bottles (like the MSR fuel bottles) are specially designed/treated for fuel. You're not supposed to use the MSR fuel bottles for food/water/anything but fuel, so that leads one to believe there is something special about them. If you do use this for fuel - be sure to never use it for anything else again. Also, I'd check that the fuel pump for your stove fits on the threads.
