Flying the B-314, Corrosion
Aluminum and salt water corrode rapidly. Boeing's great engineering dept. minimized this by specifying-Alclad,anodized, zinc chromated sheet aluminum. We had special brushes and chemicals to remove the white powdery corrosion and then we chatted the wetted areas with lanolin. We all realized the life of the airplane would be short. The bilge, or the bottom deck was especially affected, because they were a series of water tight unventilated compartments. One had fuel transfer pumps.
