Building A-75, which is connected to Building A-76 via a narrow corridor full of hooks on an overhead conveyor belt, has been referred to as the "Paint Building" for years, but sadly very little information can actually be found regarding this building.
The series of overheard conveyor belts, hooks and driers leads many to believe this building was where blasting and painting of parts were done during the years of operation at the Mare Island Naval Shipyard.
