Water and dirt repellent windshield
*
With this windshield (not released at
this time), a specially-smoothed surface
causes water drops to bead up and run
off, thus carrying particles of dirt with
them.
Traditional windshields, even when they
are in new condition, have a microscop-
ically "rough" surface (1). The surface of
the water and dirt repelling windshield
is smoothed with a clear transparent
fluid.
Depending on the cleanliness of the
windshield, the water beads up and
runs off at approx. 40 mph (60 km/h) as
a result of the air flow (2). The coating
has no negative effect on vision through
the windshield because it is completely
transparent.
