Abstract : Replicate specimens of coated steel test panels were exposed in Kwajalein, Marshall Islands, Kaneohe, Hawaii and Port Hueneme, California. Two test sites were within the Tropical Zone and was about 10 degrees north of this zone. Coating performance was correlated with the variations in weather conditions at these test sites. A rule of thumb was postulated for classifying coatings as poor, acceptable or excellent relative to their concurrent performance at Kwajalein and Kaneohe. A paint that does not fail at either Kwajalein or Kaneohe after 3 years of exposure is considered good to excellent, depending on any evidence of serious deterioration along the scribe as well as the condition of the unscribed specimen. If a paint fails at Kwajalein but has not failed at Kaneohe during 3 years it is acceptable. (Author, modified-PL)
