Instructions are kinda blurry on the blue. It recommends Gunze 20, which is enamel, or Tamiya XF-8 which is, looking at the color charts obviously incorrect. So now I'm trying out Gunze H67, which is RLM65 for kraut planes.
On top of that the very, very few pictures of the originals are kinda sketchy too. They showed up a few times in Germany till 1994 when they were sent back into Russia, then they disappeared. Likely they were repainted before the unit took part in the 1995 Chechen boogaloo.
So I'll mostly have to play this one by ear, unless someone finds a wreck in a field somewhere.
