A process is provided for coating a given surface of a heat sensitive metal article e.g., thermally massive aluminum with a high-cure-temperature-coating-forming powder. A first oven heating step elevates the metal articles temperature to a predetermined preheat cycle high-limit-of-heat-load-temperature. After a first predetermined period of time, the metal alloy article is withdrawn from the oven. A high-cure-temperature-coating-forming-powder is then sprayed onto the given surface of the metal article. The spraying, comprising first and second spray sequences, is initiated essentially immediately after withdrawal of the metal article from the oven. Author
