Mention has been made a couple of times about the race car the Petty's ran that had a vinyl top.

Both Richard and Kyle have told the story of that car in detail. It was at a time when the teams were acid dipping the car bodies to reduce the weight above the CG of the car and that was part of the whole story. It was also at a time when nobody had much understanding of aero.

They did not do the top that way for aerodynamic reasons. Their ''punch line'' is that in fact the vinyl came loose and blew open in front. They chuckle about the irony of that.
