Call Jill Jasek, at Sierra: 800-288-7234.  She's anwered all of my
questions to my satisfaction about Sierra and its properties. I use it in
my '84 Westy, including  the flush product and the hydrometer (?) used to
test, and to date, after about about six months, I've had no evidence of
any deterioration. If you are still concerned about rust and corrosion
inhibition,  ask her for a source for comparative data and information,
which I assume she has available.
