I used PPG paint through my gun.

John, by "the inside of the wheel" do you mean the back side that bolts against the drums/spindles? If thats the area youre referring to then I got pretty close in that area. I didnt mask off the wheel and just let the silver flow through the holes.
I didnt post that pic because I didnt think anyone would care and the overspray is hard to see, just looks like a bad pic.
