RE: Wiper airfoils

["John Wiltshire" <John.Wiltshire@domain.elided>]

"FWIW, often the wipers on older Italian cars had a pair of wires running
the length of the blade rather than a bent U-channel of sheet metal. This
would reduce the surface area, thus (presumably) the aerodynamic lift on
the assembly.... (besides, they looked good!)"


I remember these on my Dad's Berlina back in the 70's.  They were available
as aftermarket items from Trico called "Speed Blades" or something like
that.  They were sold exactly as Ron describes - ie that the wires
presented less surface area and so were less prone to lifting at speed.
