I honestly must disagree. As much as I see your point, it just doesn't feel right at all. And realistically, it isn't right to keep it clean. Even at places where the F-14 cockpit + body are preserved and kept on maintenance, there is still exposure and you can see the wear on it.
You can see the wing sweep handle here and landing gear lever with this showing, and even the labeling.
There is also chipping of the paint, which (as was said by Robert) did not get placed on steel, but aluminium.
