Dot Filtering and Fading Question

To my eye, I like the subtle hues added to the final, post-faded olive drab, that dot filtering adds.  

I would do the base coat first, then lighten it in whatever manner you choose--I do mine with an airbrush. Add the dot weathering after that. The only other thing you should need to do after that would be pin washes. THEN add weathering like pigments and dirt.

The dot weathering method in its original intention uses primary colors--red, blue, yellow, white--to bring about barely-perceptible tonal shifts in the paint. It should be almost unnoticeable when done properly. It's NOT the same as overall tonal filtering. If that's more of what you're trying to get, just add normal filters in common weathering tones.

Thanks for the replies, this helps.  Doog, the dot filtering technique is the one I want to do not overall tonal filtering.
