I looked and it appears I do have a hydro-dip company in the area, but they seem to specialize in camouflage and carbon fiber finishes. Their metal finishes on their website are smooth like paint out of a paint gun.

Powder coating place has hammertone finishes, but they don't look quite right as they are silver with black, red, blue, or green mixed in. I have seen spray cans at Home Depot with some fancy metal like finishes so maybe I'll look into those.

Right now a solid bright silver color with alternating shades of silver/grey on top is what I'm leaning towards. It needs to warm up a few degrees to be able to mess around with paint though.
