Well, modern kits use clear a/c as the best paint for clear canopies is still none at all.
Now, given how soviet a/c often have less glass than their western bretheren, this might not be quite so obvious. Does maks a nive effext on items like helos, though.
I want to remember that Soviet naval practice used a red linoleum on their decks. That red I have seen described as being any thing from a "hull" to a "brick' red, and likely every shade between or besides. The models that have looked best to me used a color similar to Humbrol leather, although a more "roan" rather than chestnut hue might be apt.
That help any?
