I have checked the posts on this subject and I want to make sure that I have this correct. I want to clarify how that back side of both valances would appear after paint.
The front valance panel was painted off line with the hood, front fenders, etc. It received a coat of red oxide, gray primer and then the top coat of paint. Since it was hanging and the operator had access to all sides of the part, it seems to me that the back side would have, or could have a reasonably good coat of each of the paints. But if not, one could see the red oxide, the gray primer and the top coat on the back of the painted valance.
The rear valance arrived at the plant with a red oxide primer but not the gray primer. The rear valance panel was installed after the car body received the gray primer. The valance was hanging down and attached loosely by the top screws. Therefore after paint, the back side of this part is predominately red oxide with only overspray from the top coat which would have been through the backup light holes and the sides where the part was not attached to the rear quarter panel.
Do I have this process correct? Thank you.
