[s-cars] [Fwd: Re: Bosch Icon wiper blades...wiper blades (sing along)]

The original design of the blade has a convex curve when it is lifted 
from the windshield.  This is so that the center of the blade will have 
more pressure against the glass and will resist lifting.  If you take 
this out, the center area will lift at higher speeds.  You have just 
defied years of wind tunnel testing to get the blade to perform 
properly.  Let us know how it worked.
