### Coil-applied organic coatings shall conform to the AAMA performance class indicated in the datasheet, applied over the pretreatment and primer the coating manufacturer specifies for the substrate.
### The three AAMA classes are distinguished by the length of South Florida exposure the coating must survive within stated limits on color change, chalk, gloss retention, and film integrity: one year for AAMA 2603, five years for AAMA 2604, and ten years for AAMA 2605. Longer qualifying exposure buys longer service appearance and costs more per square foot. {note}
−### Where the finished face is exposed to direct sunlight and is visible from a public way or an occupied space, the coating class shall be not less than AAMA 2604.
+### Where the finished face is exposed to direct sunlight and is visible from a public way or an occupied space, the coating class shall be AAMA 2604 or AAMA 2605 unless the datasheet accepts AAMA 2603 for that face.
### Where the coating is selected in a saturated or organic pigment color, the Contractor shall obtain the coating manufacturer's specific color data, because color change limits are more difficult to hold in those pigment families.
### The Contractor shall confirm coil order quantity, color, and lead time at the time of submittal, and shall report to the General Contractor any lead time that affects the construction schedule.
