Also, I've heard the orange stuff should *not* be used in anything with a
copper/brass radiator, because it corrodes the solder.  Not a problem for
most Vanagons, but I know that there are some aftermarket copper radiators
kicking around, so...

This is probably why GM forbids using the orange stuff in any of their
cars that originally came with green coolant.
