Hell of a drivers open window Left Arm Tan! Lot of wheel time, from the time the photo taken, mostly in daylight. From before then running unbonded, always at night (and a neon tan, pasty white, then).
While some of that no doubt is a tan, the majority of it is just good old southern red dirt. Hickory Speedway was a dirt track until 1967.
