Given their smaller size, I decided against using the Tamiya aerosol cans I used in the SSD build and instead went with standard Tamiya paint. Luckily for me, I chose relatively easily matched sprays when painting the SSD; Gunship Grey (TS-48) and Haze Grey (TS-32).
Tamiya Dark Grey (XF-24) is a pretty close match to the Gunship Grey so I decided to use that as the color for the dark panels on the ships. I applied it over a black primer coat on the models, leaving some of the black showing through in recesses for shading.
After the Dark Grey dried, I spent a fair amount of time applying tiny pieces of Tamiya masking tape randomly across the surface to give the ship an Aztecing effect. Of course, this isn't true Aztecing, which is a repeatable pattern, but the effect is similar; making the surface appear to be made of of lots of individual panels.
After the grueling task of applying the tape was done, I gave the model a coat of haze grey made by mixing Tamiya RAF Ocean Gray 2 (XF-82) and Mr Color Flat White (62) mixed at a 1:1 ratio. I removed the tape and then gave the model another couple of coats with the haze grey heavily thinned to tone down the dark panels and make everything blend in a little better.
After I do this on the other ships, I'll move on to painting some of the raised details in a lighter grey and applying various washes to bring out some depth in the model.
