Allow me to apologize first for not doing any paint progress pictures.
To review the Vallejo paint set, I'm not entirely impressed. If you decide to follow in my shoes, I suggest you skip Step 4, unless you want a very brown tank. Vallejo Model Air Olive Drab is a very nice RLM 81, however, it is a pitiful Olive Drab. So after the first attempt which followed the Vallejo instructions and resulted in a rather ill looking tank, I did what I should have done in the first place, summarized as follows:
Step 1: Spray Yellow Olive along panel lines and in recessed areas.
Step 2: Spray US Light Green in middle of panels and exposed areas.
Step 3: Spray US Dark Green (which is actually a nice olive drab color by the way) in light coats over entire model.
That looks better! :)
So, as it stands, the Big Easy is preshaded, painted, futured, decalled, washed (the dirty kind, not the clean kind) and is set aside to dry.
