What is the correct stock color of black (flat, semi or high gloss) for the valance over the rear window? My car is a Deep Red ‘85 P type and the hatch is deep red. Also, should I clear coat the valance? It seems like I have seen them fairly flat. The previous owner painted it glossy black... with a paint brush. It looks ok from 20 feet but you can see the brush marks up close. Ha.
