Driveshaft stripes - sprayed on or brushed?

[Mr70]

I saw a Van Nuys SS Chevelle,that had less then 22K miles.It had overspray inches away from the VERY smooth stripes,as if to indicate it had a template over it,and then absorbed the overspray farther down where it was exposed without the template.
I saw a Camaro driveshaft at Jefferson,that was similar to this.The seller said the car it came off,was a Van Nuys Camaro,in the Car corral that day..
