Cylinder head flow - What is crucial in a stocker?

In the 1980's when I was involved with IMSA and SCCA road racing with the Mazda Factory Team, we were applying an industrial spray-on wax to the car paint finish that was manufactured by either Dow or DuPont, called Microfill. The intent of the wax was to fill the microporosity of the paint, enhancing the airflow over the body surface of the car. As I was told at the time, Mazda had discovered some aero improvement in the wind tunnel by applying the wax. At the time, the cars were being painted with DuPont Imron Epoxy Paint.

Nowadays, there are many products that contain nanoparticles with a ceramic compound that may do the same.
