Well, here is the deal. When my dad saw me watch someone weather a KI-84 Hayate with oil and enamel paints, he said to me "That looks so dirty. Airplanes should look clean, not dirty." So, I tried to argue that actual planes of WW2 had weathering on them. I tried looking for old photos, but it was not enough to show that the plane has been weathered.
So, where do I find reference photos for my airplane scale models? I say this for reference, and also to prove my dad wrong.
