This is a custom paint build using the original colors, but making it more subtle. Using light gray instead of white levels the saturation with the other colors to balance the color scheme. Everything is out of the box, including the decals.
The 1/100 MG Wing Ver. Ka is quite an old kit and it has a few minor quirks. The sticker decals are thicker compared to later Bandai releases which makes them harder to hide. Plus, they are a challenge to position as they are not precisely cut to match the surface of the kit.
