Faux Woodgrain Lodgepole Pine on Galvanized Steel

This is a 10′ piece of galvanized steel ductwork, painted to look just like a hand peeled lodgepole pine log.
I researched colors, patterns, and layers to achieve a convincing lodgepole pine effect to be applied over 340 linear feet of pipe.
The steel is first etched, then primed, painted the base color, and faux woodgrained with 5 layers.
