A method for repairing an oxidation and corrosion resistant coating, comprising: applying a first coat of a repair material to a damaged portion of the oxidation and corrosion resistant coating, wherein the repair material consists of, in weight percent to within ±2.0%, 43% aluminum powder, 47% water, and 10% metal silicates, wherein the damaged portion of the oxidation and corrosion resistant coating exposes a portion of a metallic substrate; drying the first coat of repair material; applying a second coat of the repair material in the damaged portion of the oxidation and corrosion resistant coating; heat curing the repair material; and burnishing the repair material; wherein the oxidation and corrosion resistant coating comprises at least one of: a first material comprised of, by weight percent to within ±2.0%, 37% to 46% water, 14% to 18% phosphoric acid and reaction products with aluminum hydroxide and chromium oxide, and 40% to 45% uncoated aluminum powder; a second material, different from the first material, and comprised of, by weight percent to within ±2.0%, 30% to 50% aluminum powder, 10% to 20% phosphoric acid, 5% or less chromium trioxide, and 1% or less chromium hydroxide; or a third material, different from the first material and the second material, and comprised of, by weight percent to within ±2.0%, 40% to 50%, aluminum, 10% to 20% phosphoric acid and reaction products of aluminum hydroxide and chromium oxide, and 40% to 50% water; and wherein the repair material is chromate-free. applying a first coat of a repair material to a damaged portion of the oxidation and corrosion resistant coating, wherein the repair material consists of, in weight percent to within ±2.0%, 43% aluminum powder, 47% water, and 10% metal silicates, wherein the damaged portion of the oxidation and corrosion resistant coating exposes a portion of a metallic substrate; drying the first coat of repair material; applying a second coat of the repair material in the damaged portion of the oxidation and corrosion resistant coating; heat curing the repair material; and burnishing the repair material; wherein the oxidation and corrosion resistant coating comprises at least one of: a first material comprised of, by weight percent to within ±2.0%, 37% to 46% water, 14% to 18% phosphoric acid and reaction products with aluminum hydroxide and chromium oxide, and 40% to 45% uncoated aluminum powder; a second material, different from the first material, and comprised of, by weight percent to within ±2.0%, 30% to 50% aluminum powder, 10% to 20% phosphoric acid, 5% or less chromium trioxide, and 1% or less chromium hydroxide; or a third material, different from the first material and the second material, and comprised of, by weight percent to within ±2.0%, 40% to 50%, aluminum, 10% to 20% phosphoric acid and reaction products of aluminum hydroxide and chromium oxide, and 40% to 50% water; and wherein the repair material is chromate-free. a first material comprised of, by weight percent to within ±2.0%, 37% to 46% water, 14% to 18% phosphoric acid and reaction products with aluminum hydroxide and chromium oxide, and 40% to 45% uncoated aluminum powder; a second material, different from the first material, and comprised of, by weight percent to within ±2.0%, 30% to 50% aluminum powder, 10% to 20% phosphoric acid, 5% or less chromium trioxide, and 1% or less chromium hydroxide; or a third material, different from the first material and the second material, and comprised of, by weight percent to within ±2.0%, 40% to 50%, aluminum, 10% to 20% phosphoric acid and reaction products of aluminum hydroxide and chromium oxide, and 40% to 50% water; and wherein the repair material is chromate-free.
