I’m building a couple 1/48 scale jeeps (one Hasegawa and one Tamiya). My questions are these:
When applying the dot filtering, is it best to do before lightening and fading the OD coat, or fade and lighten and then dot filter?
Should the dot filtering be done before any other weathering, like washes, etc.?
The Hasegawa jeep will definitely be a Pacific Theater USAAF airfield jeep for a diorama with a P-40N. The other will be floater, maybe ETO airfield. Here is a link to the most recent update for these builds.
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.
