## Exterior touch-up is harder to blend than interior because the in-place film has weathered, and material from the same batch, with the formula recorded, is the closest match the Owner will ever get; a gallon of each color serves the first few years of touch-up on most buildings, and more is delivered where the Owner's maintenance staff will touch up rather than recoat. {note}
