But seriously.. Mission:SPACE had an exterior paint job that cost $500 a gallon (and obviously used more than just a few gallons.)
Hard to find a good pic, because it had such a short life, but that iridescent purple ombre was one of the "marks of quality" on what was an extremely expensive and "well designed" attraction.
As soon as it became an obvious failure Disney pulled the money away from it and that paint was never purchased again.
