Paint in US Navy service was actually considered a "preservative coat" more than strictly camouflage. In the Navy filing system used up to and through WWII Camouflage was designated S19-7, with
S19 being "preservative coatings." Any deck coating would have been tested and graded for its preservative qualities. I just don't have a lot of good pre-war documentation yet. I've spent most of the time allotted for it looking for "Construction & Repair No 4." which was essentially the 1930s camouflage manual.
