I am making a plate to cover up the radio opening in my 69 stang. Starting with a 1/4" alum plate, mill the perimeter to size then put a 1/8" radius on the outside, then send it out for black anodizing. When it's back I will then etch the text and running horse with a 1/16" ball end mill. Then very carefully paint the etched areas in with red to match my black & red interior. Think it looks ok? Here is a screen shot.
