Must have cost a pretty penny :)
FYI, as you see in the video, a semi-truck deliver's the paint. Think for a minute how much a single five gallon pail of typical house paint weight's.
If I recall correctly, you lose approx. only 2 % (percent) of weight to evaporation, via application of paint.
At the time of my working at Boeing,(1986-1991) a 747 had approx. 50,000 {fifty thousand, not a mis-print} pounds of paint on them, and they (Boeing) were trying to cut that by a mere 5 % percent. Now you know why American Airlines doesn't paint the outside of their planes.
My guess at the cost of that paint / refinish job, 2 - 4 million dollars, should get you into the neighborhood. What they show as coming out of the delivery truck (i.e., paint & primer, etc.,) my guess 1/2 to 3/4 of a million's dollar's. Won't be surprised if it totaled as much as 1.25 million or just a little more, I've been out of the game of purchasing anything autobody wise.
