John,
I agree with Your suggestions, but there is a LARGE difference whether You want to dress it with a cammo scheme, or a shiney one like the Frecce Tricolori paint scheme. Any imperfection will be seen on these glossy surfaces. And for durability 2 K lacquers are way better as waterbased ones. To get optimum result You need a high quality spraygun. Of course I started long ago with a cheap one, but after upgrading in steps with better equipment, I found that the end result improved every time. The expensive ones make much better fine spray as do cheap ones, thus reducing the risk of droplets (or is the correct wording "sagging"?)
Professional spray guns operate with 2 Bar pressure, which is 30 PSI
An expensive plane like the MB needs a nice dress
No good to go the easy way out on this one.
