Camouflage is approximately 3x more than a single color repair due to using 3 colors or more, pattern, application of 3 colors, and 2 pattern layers.
Essentially its the same as coating one gun 3 times (labor,application,materials) in addition to the time and experience of placing the patterns in between layers.
In addition to the above each layer needs to be flashed in oven requiring 20 minutes in the oven and 30 minutes to cool. Easily adding 3-4 hours on each job. Also requiring additional taping, cleaners,thinners (to clean between colors etc).
