my thoughts exactly. if Bubba starts spraying that crap all over the
place, who
knows what it would do to a vinyl headliner or plastic air
conditioning cover ...
or worse yet, skin. if we were to use that stuff at home, -45 degrees
F will
produce instant frostbite ... and frostbite is NOT something you want
to have
happen to you. it doesn't go away. and sometimes, if it's really bad,
you have
to have it surgically removed or gangrene will set in. :(

and what about wiring insulation? i really don't think it's designed
to stand up
to that sort of temperature, especially if the stuff were sprayed on a
warmed up
electrical system or cooling system or even engine. :(
