Matt - I used a flat gray and flat white Krylon primer for undercoats. For the lower hull I used Krylon Red Oxide, the upper painted with Testors Red Gloss. Decks were painted with Testors Gray. I used Testors enamel bottle paints for grays, white, and blacks. For all of my deck fittings and towers, I used White Ensign Models USCG Spar paint. I then sprayed everything with a couple of coats of Dullcoat to flatten out the finish. I used this site as a guideline to try and stay accurate (as much as I could) with paint scheme of these ships.
