I can't find anything in any of the books or online showing a full shot of Jandina IV.
Based on photos of other Js with the 80th flown by the big guns like Ken Ladd, Cy Homer, Corky Smith etc that do have photos of the entire aircraft, I'd go with an Olive drab antiglare panal on the nose and wings.
The one photo from the 80th site seems to show it fairly clearly.
I'd skip the wing tip green and white. No evidence to support that anywhere. The mid wing ID strip didn't arrive until January of 45 and that was when they had L models so that wouldn't be there.
And I think I'd go with the two tail boom stripes like the decal sheet shows.
Just my suggestion though
