RSK with windshield wiper on the inside
 

I was saw a video of an RSK (I think) on the The Carousel at the Nurburgring from back in the day. It was foggy and the open car had wipers running on the outside and INSIDE of the windshield.

Has anyone else seen this on any Porsche or have a photo? I have a friend thinking about it for an open speedster outlaw project.

works well when you don't have defrost heat handy
There is an in car video of Stuck at Sebring in the rain, racing a turbo GT2. He did not have the luxury of an interior wiper so had to make do with a rag on the back straight at 150 plus!
