Oh Lordy, I now own a Fordy (a Lincoln actually)..

I cleaned the driver's side inner fender with some diesel fuel on a rag. It cleaned off the old residue nicely and was glossy for a day and then it absorbed into the plastic and that is what you see now. I haven't cleaned the passenger side yet.

It's an odd engine compartment/hood hinge setup. If you look closely you can see that the passenger side hood hinge mounts inboard of the hood's underside frame structure by about 6 inches, while the driver's side hinge mounts outboard of it, directly to the inside of the fender. That is why there is that black section that is bolted to the upper inner area of the passenger fender.
