1965 Dart Grill - How Shiny?

After stripping I will need to sand to get rid of pits and scratches. I guess I could sand in the direction of the extrusion (lengthwise) and just not polish. The trick will be deciding what grit to end with. Another option could be a light media blast after sanding.

It seems like the top and bottom of the grill is shinier than the center portion. Perhaps I will polish just those parts.

My trunk panel is quite a bit shinier than my grill, especially on the back side, but I guess that could be the result of less exposure to the elements than the grill would receive in the front of the car.
