Harvey, I just looked at one of my original rear splash shields and it has undercoating on the front. An area on the front where the undercoating has come off and it has black paint on the front and completely black on the back side. John
They are both painted black and covered in undercoating. Of course the undercoating coverage would depended on the factory worker. Some were heavy and some were thin. The pattern below was replicated from the original. I don't have a picture of the rear shield. It appears shiny in the picture but it was actually dull.
