Also, except in the worst of conditions, anything readily reachable was kept in good paint.
The hull could show some rust, some wear, but, "worn" spots spots should "show" as neat rectangles of new paint (or primer, if interrupted).
In USN practice, there is an entire division of the crew dedicated to topside activities. The Deck division gets the task of scraping & needle-gunning worn/chipped paint to bare metal, then priming that repair, and painting over that in the prescribed color of paint.
It's dirty, hard, monotonous, mind-numbing, work with strong chemicals and complicated surfaces, all on a moving vessel subject to drills and alerts. It is great fodder for the hands to generate most excellent griping. It is the measure of the officer commanding in how much of that griping is good natured versus unfettered B&M/whining/real distress. As with any deceptively simple task, it needs doing well, and with the full "buy in" by the personnel involved.
Oh, and painting often gets 'better" the closer to the bridge on some ships--this is not always the case, but it is one that can catch the eye.
