This evening I cracked out the Artis Opus brushes and set to work dry brushing anything undercoated black.
As you can see the majority is grey apart from the wheeled vehicle. Bet you can’t guess what colour it is going to be.
I am wondering about this two tone approach. The base underpainting tone followed by the white and then the Speedpaints. I should maybe do a test on a couple of identical miniatures. To be honest it is the time it takes for the paint to dry so it isn’t a huge additional amount of time…Not to mention that I don’t normally go down the underpainting route. In the past it would have been white undercoat and the speedpaint style paint over the top.
Hopefully I will get the white on there tomorrow and then onto the painting.

If you are going for a grimer look, you’ll like the effects of a zenthal drybrush under the speed paints. From what I see in the photos, you will need to bring up more lighter tones, otherwise the speed paints will look more black than darker shades of color. This is what I have found, it will be interesting to see your results.

I am going to put white dry brush over them all tonight. The main question I have is whether the coloured first layer actually makes a huge difference.

I’ve found that starting from black, that the black stays black, so mach sure it’s only in the areas you want black. Darker greys are similar, in that they stay mostly grey. lighter grey and white set the color. That being said, my experience has been that the model overall looks too dark. I start with a medium grey primer and work up to white or a pale sandy color. UMMV.
