I was concerned about how many things are done, and how to try and replicate the finish. Ford calls out finishes on the fasteners, that eliminates that issue. However, as Bob and Jeff have mentioned numerous times: If it looks right, they don't care how it gets there. I, for one try and find a finish on parts that replicates the factory, but yields a more durable finish being my vehicle will be driven. Many tried and true processes are passed along, and as one of us stumbles upon something better, it becomes the norm.
The best we can do now if we want that assembly line new look is to try and replicate from the few survivors that are left. There in is what we use to gauge.
