on a tour though the Boeing factory we where told one 747 they put 600 gallon of paint on the airplane,thats around 4000 lbs.when its being painted the wheels are on scales!
John Dieana said something to me about paint weight on race cars years ago, I would like to see the before and after weight of a car without paint and then with paint due the evaporation of all the liquids n the paint BTW, we call them stripe takers out here, not pecker extensions
the evap will vary just the way a guy sprays.. I forgot the numbers on my car.. I have painted it 6 different times but sanded back to metal each time and if I recall right it only varied like 6#.. that was a base/clear with a sealer each time
