Is that the weight of solids remaining after application or the weight of paint with solvents and carrier?
Aircraft (large Boeings anyway) are painted with polyurethane paint, in effect they are coated in plastic which on a 747 adds up to 'quite a bit' - a few hundred kilo's. Its a two part mixture and cures via chemical reaction between parts A and B. Not via the evaporation of solvents so only a minute amount of weight is 'lost' from the paint mixture during the curing process (Judging by the awful smell in the hangar during painting at least a little of the mix ends up in the atmosphere/lungs)
