Not since I hurled down the rear window of a friend's 60's Pontiac convertible. It was impossible to completely get out and would stink on hot summer days. He hosed it down, dumped some mouth wash and it still smelled. He waited until the weather was colder and sold the car.
My only excuse was that I was home on leave just prior to heading for my paid vacation off the coast of Viet Nam. I still apologize to him everytime I see him.
