Hood's corrosion control and routine dry docking

Did the absence of a major refit mean Hood's corrosion went untreated?

No. Dry docking, hull inspection, and repainting were routine maintenance performed between major refits.

Hood regularly entered dry dock for paint removal, hull inspection, and repainting. Docks capable of taking her existed in Britain and Malta. This work belonged to routine maintenance and did not require a major refit. Crew painting continued between dockyard visits, while dry docking allowed the underwater hull to be treated properly. The absence of a major reconstruction therefore does not establish that ordinary corrosion control was neglected.
