RE: Rain-X
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.

BTDT and it is impressive, especially at night.  You can't eve see the rain,
it just flows off the windshield.  And this all reminds me I need to freshen
usp my windows.....
