Bare carbon steel (CS), galvanized steel (GS), copper and anodized aluminum (Al) as well as painted CS and Al were exposed to the atmosphere of Kuwait at 85 sites. The exposure was for six and five years for the bare and painted metals, respectively. Polyurethane, acrylic water-based and acrylic solvent-based enamel paints were used in painting CS, while sprayed polyester powder was used for Al. The performance of the bare metals was evaluated through weight loss measurements, while the performance of the paints was evaluated by measuring loss in gloss. Rust grade and rust creepage at scribe were also measured for painted CS. Time of wetness sensors and chloride candles showed low to moderate values. The corrosion rates of CS and GS were mostly low. Corrosion of these alloys appeared primarily controlled by humidity and airborne salinity. With regard to copper, the corrosion rates were mostly high and were mainly affected by sulfur gases. The anodized Al suffered sand erosion in a few places. All paints suffered severe loss in gloss, while there were little rust spots and rust creepage for painted CS. The results were attributed to the arid desert nature of the country and the types of industrial activities.
