First I painted the entire airframe a lighter gray. Adding 0.6g in the process. Preperation paid off as the paint weight came out pretty good. I used Tamya Acrylics in the little jars, thinned, and airbrushed for the lightest of all applications. I couldn't help myself and I did a god color coat, after I sanded with some 600 grit paper, but that did not remove weight, just color.
