The closest I found to the "Magic Wash" formula was 1 part future, 4 parts water, and "a few drops of your favorite pigment". A few could be anything from 2 to 7. In testing wash formulas I've found 1 drop makes a huge difference in how dark your wash is. Just saying "a few" doesn't cut it.
To get my "parts" I use droppers. I use this when airbrushing as well, to mix my 3:2 paint to windex formula.
For flesh I use about a 1:2 or 1:3 W&N peat brown to magic wash.
If anyone else would like to share some EXACT wash formulas I'd be super interested.
After all the wash, I do a dry-brush highlight of everything. Usually a 3:2 base coat to white. I keep finding I have to do it lighter highlight then I would think, because my matte varnish really lightens things up, and the highlight disappears there isn't enough contrast between the base coat.
Up next will be my decal tutorial.
