Most of you have probably heard of
Army Painter's Quickshade. It's a varnish with pigments added to it, that protects your paint and shades your minis. Some love it, some are against it. Pro painters don't need it, but painters with less experience or no time to paint might find it very usefull. My experience is that when applied with care, you get great results. I'll give you some examples so those of you that don't know what this is, can see what it does.
I've painted some zombies from the Mantic box
Mhorgoth's Revenge, using the dipping technique (= Army Painter's Quickshade). I speedpainted them, very sloppily, just slapped on the skin colour after basecoating them bone white, then painted on some colour for the clothes, eyes, blood, bones sticking out, the tile base etc. I just threw on the paint, thinned it a bit, so some of the colours would blend (to get a bruised purplish skin on some places). I use acrylic paints from Citadel and a wet palette.
Then I let it dry, and I dipped them in the Quickshade. I brushed off some of the excess dip, and let them dry. The result is actually quite good:
The after pictures were taken when they were still wet, after they dry, it looks a bit lighter. These were my first tries with Quickshade, and after these I decided to apply the dip with a brush. That way you can dose the stuff better, gives you more control. The zombies on the grey tiles were painted afterwards this way:
I've painted them a bit more precisely, and used a small brush to apply the quickshade dip. After letting the models dry for a day, I sprayed them with 3 very quick/thin layers of
anti-shine matte varnish spray, which makes the shine go away completely. After that dried, I applied quickshade with a brush again, but only on the bloody parts, to make the blood and gore more shiny and wet-looking. The result is amazing:
