Decorated sheet metal and metal laminates should never be stored in high moisture areas, even when still crated. Special care in storage should be given in hot and humid marine and tropical environments. Storage temperature should not exceed 85º F (30º C) or go below 50º F (10º C) for long periods of time. Optimal storage conditions are approximately 70º F (21º C) and 50-60% relative humidity. Clear coated metals are especially sensitive to heat and humidity as it may result in condensation under the peel coat edges and in trapped air bubbles. Generally, all clear coated metals should also be protected against ultraviolet light to prevent discoloration and potential failure of clear coatings.
