We used it in the USAF on the glass on our fleet of KC-135's, for all the
years that I was a crewchief.  It was a mil-spec version of the same exact
main ingredient as is in Rain-X.  Just realise that the wipers do wear away
that area, so, it does need to be reapplied every so often; you'll know when
it's time.
   Sometimes, we'd drive down the highway in our Rain-X'd POV's, and not
even need to turn on the wipers, it's that good.  The airflow over the
windshield at highway speeds over a fresh application of Rain-X, would be an
awesome sight!  The rain just streaks across the glass and flys off.
  BTW, don't use their windshield washer fluid with it inside; it's a waste
of money.  Just apply it by hand to the outside of your window.  They also
sell an anti-fogging product to be applied to the inside of your window.
  This stuff  would have come in handy, back in the 70's when I was
daily-driving a Beetle with no working defroster.
  Anyone else have good stuff to say about this?
