I smoothed out the areas that needed a little extra Bondo and re-primed those spots. Next comes paint.
To make the screen mount match the pattern of the vinyl on my dash, I decided to try a hammer finish paint, followed by a flat black coat. Here you see the first hammer finish coat, then the black coat. The black separated like the hammer finish, which is not what I wanted. I'll try again tomorrow after it dries real well.
