For Aerowave 2001 you just mix the parts, stir and then spray. I have used about 6 liters so far, with wings and tail done, about half way into the fuselage. I would guess that at least 25% of that is wasted either left over due to over-estimating how much to mix, or from overspray. So lets say 6 liters ends up on the aircraft - that's about 6 kg or 12 lbs. I don't think it's too bad given the protection it provides.
