The masking phase was a long, time consuming one... Because I wished to do some colors effects, using the Citadel Color orange (lighter than the Game Colors one); darkened the Game Color orange on some other panels and finishing with a marron brown.
You can see the result. I'm a little bit disappointed because the difference between Citadel Colors and Game Colors oranges is visible only when your eyes are at 10 cm of the model (see photo nr16)... But I like very much the "gun panels" made with two drops of marron brown in the orange.
Now I will have to paint the pilots before to continue on the aircar...
