I'm trying to recreate the paint scheme on an Air America C-45. https://www.utdallas.edu/library/specialcollections/hac/cataam/Leeker/aircraft/vtb.pdf
The model is the 1/72 Hobby Craft C-45-H. I'm wondering how to create the thin white stripe between the dark blue and the blue-gray on the side of the fuselage. No decals are available. In scale, the stripe will be maybe 1 mm wide, and it curves gently downward toward the nose and sharply downward toward the tail. To me, this will be a real challenge. Does anyone have any tips on how I might do it? Masking? Decals? Magic? Anybody?
