For two stage two color with light clear just enough to shine out the orange peel on a 40% CA300 about 15-17 oz's.
Two Stage two color uses 23oz of color fluid and just at 19 oz of clear fluid.
Single color you could get away with about 25oz of fluid one color entire airplane but the weight would be about the same as two stage due to the heavy pigment.
hope this helps.
