Best way to do a camo hull without an airbrush is as follows:
Paint your hull and superstructure before you glue them together.
Paint yout deck before you attach anything else to it.
Always paint the lightest colors first, then the darkest. as dark paint covers light paint easier than the other way around.
Take your time, and if you get frustrated, walk away from it for awhile.
Do you have the drawings of her camo pattern and the colors she wore? If not, head over to my website and look around in the gallery, there's a few models of Prince of Wales over there. www.modelwarships.com
