I have heard, and have a book that claims, that all Mustang wings were primed and painted, with rivet depressions filled, to allow laminar flow. A photo in the book shows a wing at the factory in prime.
However, I have other photos that show units in 1944 that are natural finish, including wing tops. So I assume that sometime prior to late to mid 44 they dropped the painting of the wings. Does anyone know when this occurred?
I am building a Hasagawa 1:48 plane of the 20th Fighter Group, which was equipped with Mustangs in 1944, and I am intending to alclad the plane. I want to make sure that these planes did indeed have natural finish on wings.
