I have read a bit about airbrushing on a darker color than the your base color before applying the base coat and then when you apply the base coat you let the darker undercoat show through at the egdes of panels and other areas as well. Can someone please expand on this style of finishing armor? I was looking at guntrucks photo album and remember reading in there that he does something like the above mentioned. If there is an article somewhere here please point me in the right direction. thanks.
