Testors 4226 is a dark sea blue and is appropriate for naval aircraft of the period. It is inappropriate as 5S Sea Blue of the Pearl Harbor period. (The problems of calling color by a generic name)
I'm not even sure that Testors made the correct Sea Blue (5-S) in their now out-of-production line of acrylic paints. I know that they never did 5D Dark Gray, the color which the Arizona was known to be in from April, 1941 to late fall 1941. Whether the Arizona was, in fact in 5S Sea Blue is still a matter of contention between historians. Likewise 5S is not in the PollyScale line of acrylic paints.
The only out of the bottle solution is the Colourcoat line of paints from White Ensign. They are enamels. Should you choose to mix your own, the Snyder & Short Paint Chips should be your standard to mix to
