For planes, I prefer spraying a base coat in a correct color. Brushed-on paints always leave streaks, lines, and uneven spots which show up on large monochrome surfaces like airplanes have.
For WWII overall glossy dark sea blue, I find Rustoleum 2x Ultracover Midnight Blue satin to be a superb match. It made me so happy to have a one-and-done spraypaint, I painted batches of Corsairs, Hellcats, and Avengers in two different scales, so many that most of them have never been on the table. 
For Korea, I used to use the Model Master Glossy Sea Blue spraypaint as the base coat, and the Model Master FS15042 acrylic bottle paint for touch-ups and corrections (e.g. canopy bars, fixing mistakes, etc.). These colors have a slight greenish hue like the post-war paint color, and the spray and bottle paints were matched to be the same color. Unfortunately, Testors discontinued them, so this isn't useful advice, and I'm not sure what I'm going to use next time I have to paint Korean War USN planes.
I think the Tamiya XF-17 bottle acrylic is a good match for post-war USN planes, but Tamiya bottle paints are terrible for painting large surfaces unless you airbrush with them. I'm a huge fan of Tamiya spray paints, but I don't think the AS-8 Navy Blue is quite the right color for post-war USN planes. If you're less particular than I, it might be close enough, and it's a great paint, though very hard to match for touch-ups.
Tamiya makes two other sprays that might work for USN gloss sea blue:
- TS-55 Gloss Dark Blue spray
- TS-64 Dark Mica Blue
I haven't looked into either one to be sure, but you can do Google image searches for models sprayed in various Tamiya colors. Modelers like to show off their modeling projects.
