Wiper modification
 

Hi all! Recently changed my wiper blades and was thinking...

The Renault (amongst other cars) had a cool wiper blade which has a built-in washer jet. Instead of jetting water from the stock jets, the jets are part of the wiper. So the water only hits the windscreen and is wiped off simultaneously. Beats having water splash all over a nice polished RX.

Does anyone know whether this is available aftermarket as a mod? Make, cost and source pls. Thanx :D
