Does the silver paint weigh more that regular flat paint on an aircraft? I'm just curious that I've seen some Airbus and they have a silver paintjob and I know that unlike aircraft like the MD-80 and 737 that you cannot leave them bare and shiney like AA does, I've noticed that AA's Airbus are painted flat gray. Is there a weight or cost savings to painting gray versus silver? I'm imagining that it might take more coats or be multistep to give it the sparkle. The reason I ask is because I've seen some artist renderings of the 787 in NW colors and it looks white instead of silver. It may be an artifact of how they did the picture or my computer monitor. Just curious.
