Jankees, those look absolutely marvelous!... as fresh out of the paintshop. I was around the F-4C/D & E a lot in that time period, and the paint used then faded/weathered very fast! In just a week of use, the fading was obvious. And this was in the high desert at Victorville, Calif. George AFB, just south of Edwards AFB.
I don't remember the actual repaint schedule, as I worked in the bomb dump, but was on the flightline a lot, doing flightline delivery of ordinance. I do remember that whenever a spot needed touching up after a repair, it was very obvious as the new paint really stood out from the weathered paint. It could be seen from many yards away.
I am sure many of the old guard here from that time period will agree, but without actual pictures of elapsed time, it would be hard to get right, or maybe I should say, wrong?!
Anyways, I really like those Huns. Very well done.
