Back side of fender would be a most standard red oxide (when compared to the colors used on the floor pans and frame rails) with body color overspray (a little or allot) - more on those surfaces in direct line with the edges on the fender that would be painted body color. Example - door side edge, fender lip and lip where the head light bucket and valance would attach.
Front splash shield would have been semi-gloss black and attached after the painting process
Sound deadener would have been added at the end of assembly (car complete with no tire or wheel) and would cover at least a good part of the exposed firewall/cowl section in the wheelwell, Up the rear inner fender panel (to the top of the spring cover). Down from the front upper edge of the spring cover, down at an angle over the forward inner fender to about the front bumper mount and an application over the front and rear splash shield to fender seal.
In some cases worker would also apply a single pass of the application wand on the underside of the front fender. This appears to have been a personal choice.
The amount and coverage area of the sound deadener could be a little (as discribed above) or allot. Depending on the effort applied by that particular worker. Normally the amount matched on both sides so this may have been done by the same worker.
