I swear it happens at least once a month. Someone decides to wash their windshield right in front of me and sprays my clean car. I won't turn on my wipers because I don't wanna get the guy behind me.
So I have been thinking, 2 of my daily drivers have a rear windshield wiper and spray. With some modification to the rear nozzle, I can make it spray backwards. With a little more modification, I can add a reservoir of used motor oil and higher pressure. The idea is not to make the road slick, just tag their car with a mist of hard to clean crap like they did to me.
But there are 2 problems, drip (when the pressure drops) and the turbulence can send the oil back to my car. How do I overcome these problems?
