That link is REALLY useful. Thank you.
I've made some actual progress today. I've never, ever painted a deck. I've always cheated my way out of it with real wood.
This was.. interesting.
1) The aft and forward well decks were painted and weathered with a mixture of brown/black oil paints. I've found conflicting sources/models on the composition of these decks. Some said they were intended to be wood, others steel. I decided to go with steel, as it simplified painting and made more sense.
2) The forward and rear platforms were a REAL pain to attach. The planking didn't match up. The depth of the planking didn't match up. I glued them in place and did my best to scribe some degree of continuity. Thankfully, the aft platform appears to be grey in a lot of models. I'll do the same to better hide the line.
Process of painting the deck was as follows:
a) Painted the base with Tamiya Deck Tan. I then Futured the deck. (No picture, sadly)
b) Used colored pencils to mark some of the planking. I think I'll do this with more frequency on the next try. Dunno.
(Also forgot picture)
c) Used a 90% thinner and 10% Deck Tan to blend the deck.

d) Did it again.

e) Finally, hit it with a brown oil wash, once a Future layer protected the layers.
With some refinement, I think this will be superior to any wood deck in scale. I'm already seeing ways I can improve the idea. I still will need to paint the yellow guide lines. I'm not sure how I'll mask them.... may see if I can get a friend to make vinyl masks or I may try to see if I can make something like that myself. I'll hit the deck with another layer of grimy wash before final painting. I also need to paint the catapult tracks and other deck steel grey. This will probably be the longest portion of my painting, but it'll be fun.
Next: More deck work. I want this mostly painted before I mask it over for the main hull. Once that's done, I'll more on to the bridge, where vertical surfaces will be painted with my air brush and deck with thinned paint. Once that's done and some other small parts are added, she'll be placed on the water base.
This is sort of my plan for the dazzle:
Main paint: Tamiya Sky Grey
Dark camo: German Grey
Bow/Stern lighter portions: Modelmaster 5-P or something. Not sure here.
I'll blend the whole thing with a base paint filter, hit it with a wash, and may rust her up a bit, with scale considered.
Opinions welcome.
