I bought some of Flight Deck Decals for these decks. They are absolutely worth it, easy to apply, and are high quality. I had started painting a deck on Graf Zepplin when I bought the decal so I used LA's Awesome Cleaner to strip the paint. Unfortunately, it melted the resin around the forward mast and it fell off.
Those look great! Nice job. Care to share the paint colors you used to match up with the decals?
Of course, for Shinano I used Flat Green and Refractive Green from Vallejo, I added some black and white to both to get the different shades of green for it. On the Furious I mixed Flat Green and Flat Blue to make the aquatic green but I should have used more Blue to get the shades closer.
