Hi,
If you want to be accurate, have a look at the photo of USS Saucy at:
http://www.navsource.org
Search under Patrol Craft and you'll find her there.
The colors are 5-S Sea Blue and 5-P Pale Gray. The decks would be Deck Blue 20-B, and the underwater hull was Norfolk 65-A Antifouling Red.
We have all those colors accurately matched in our Colourcoats enamels. There is no minimum order on paints, and we ship worldwide. If you have any questions, feel free to contact me directly.
Cheers,
