1. A multilayer coated aerospace grade aluminum-copper alloy part, said part coated with a coating comprising a phosphate bonded aluminum-filled basecoat and an aluminum silicone paint topcoat, wherein the coating prevents corrosion of the part due to environmental stresses of temperature of 190°

  • C., high salt concentrations, and water droplet erosion, is resistant to deicing at a temperature of about 190°

    C., is resistant to a temperature of −

    55°

    C. for one hour, resistant to temperature of 150°

    C. for 100 hours, wherein the multi-layer coating is repairable when damaged, and wherein the repaired area is aerodynamically virtually indistinguishable from the physical point of view of the non-damaged area of the part.
