Thanks one and all. Too Kind, etc., etc.
The short version of how is this: First, two coats (maybe three) of water and/or alcohol thinned acrylic paint in complimentary colors. Usually Tamiya as first coat since they've ruined the formula for brush painting anyway. Then topped with a better brand, in my case, usually Polly or Vallejo or occasionally Model Master. After that is thoroughly dry, I give it a thinner-based oil paint wash with Mona Lisa Odorless Thinner. This thinner isn't very strong and usually leaves the acrylic paint alone as long as you aren't too rough with it. BEFORE the thinner-based wash is completely dry, I take a Q-tip, or tissue, or even a large brush and wipe away most of it, going in the direction that rain etc, would fall on the vehicles and into corners, crevices, darker areas, etc. I keep at that until I get the color I want and until the brush strokes disappear. If you don't mind the mess, fingers can even used at this point. I like the control this gives but you stain the pinkies. This wash and wipe may need to be repeated if you don't get the color you want. Edges of camo patterns are dabbed with nearly dry Q-tips or dry-brushed on to blend the edges. After that, it's whatever weathering you would ordinarily do. I will still use darker pin washes at this point if I want and pastels more often than not these days. And it's all adjustable with a clean brush dipped in clean thinner if you go too far.
It doesn't always work so well. I don't show off the goofs and careful photography helps but if you don't have the cash, the space, or a spray booth, you can get away with quite a bit this way.
Please ask if you'd like more detail and thanks again for the comments.
