Fender
Red oxide inside and out - same product
Light gray primer surfacer on exterior. Not much or any in the inside of the fender. If so most of the time it would come off when back side was lightly cleaned
Body color on the outer surface, fender lip, surface that attaches to valance, head light bucket area, fender lip and rear back edge and supports facing the door opening. With this either a lighter overspray from these applications onto logical - inline surfaces (things like back side of head light bucket area) or the painter just threw a bunch of body color on the back side somewhat blindly to cover surfaces without trying (on purpose) to cover everything. More often than not IMHO it was on the lighter side with nice coats on the rear and headlight bucket (on the back side) surfaces.
Typical nice paint application on the visible rear inner fender brace
An example of a logical overspray pattern
Top of headlight bucket area direct paint from painting the fender lip on top (red arrow). As you can see some of the paint has been removed during cleaning
Lighter indirect spray pattern (yellow arrow) from painting the lower lip of the opening (green arrow)
Other years and sometimes these years also the back side of the head light bucket area will have body color also from running the spray gun around wheel well opening painting the lip section
A little or more sound deadener much later in the build process would follow later
Hope this helps
