Bill Schoneberger of Clear Concepts Communication did the design for the wave and overall layout, based on the artwork of Tomac Henson of Epik Ink Tattoo. We tweaked the design to fit the Prius, and created separate cut files for the two layers of vinyl lettering.
(Here is a side view of the cab, before the white reflective vinyl has been applied.)
The first layer of cut vinyl was the black background for "Pipeline Cab Co.", followed by white reflective vinyl to make sure the cab name is visible at night.

(Here is a shot of the cab side, as we apply the white reflective vinyl on top of the black vinyl background.)
