You can't get any better than Dougie's knowledge and research.
If this helps at all, in either "Clear the Bridge!" (Richard O'Kane) or "Thunder Below!" (Eugene Fluckey), one of those USN captain's gets to Midway and looks at their boat and thinks something like "wow, this all black boat [measure 9 paint scheme] is practically light gray and chipped like crazy", and the same in "Iron Coffins" (Herbert Werner) for the Gremans. Basically, after only weeks at sea, all the boats got sun and salt faded and massively chipped. And paint in the 1940w wasn't as high tech as today. But the sea is harsh!
