Wing, I used the post shade method. I started out by lightening my base colors with 40% white.(except for the white, where I added a few drops of gray for the panel lines). I then sprayed the model with the lighter shades. I followed by spraying along the panel lines with the darker shade. After that, I sprayed a filter (a few drops of the lighter color mixed with paint thinner. Approx. 10/90 ratio) to blend the colors. I used Tamiya acrylics.
Med. blue, white, and black. Hope this helps.
