You won't believe this simple trick top painters use to paint entire daemon army in one evening! Just kidding. It's 7 easy steps instead ;-)
No, really, I did paint those miniatures fast in terms of man-hours spent but it still took several days because you want all the layers dry well.
I hope this will be an inspiration, and for some of you a revelation, that effects and work put in achieving them are not always related.
Others may be encouraged to get their army painted at last. I believe it's better to field simply but neatly painted miniatures than unpainted ones waiting for this big day some time in the future, definitely, maybe or not. Carpe diem! Time is the only resource that cannot be replenished, even for all the tea in China. Once it's gone, it's gone.
1. Undercoat the models white or light gray
2. Spray-paint the models with Citadel's Mephiston Red Spray. Don't overdo it, otherwise the paint will form blobs in parts of the models and hide their details. You will be able to fix white spots later
3. Fix any white spots left using a standard brush and slightly thinned Mephiston Red paint (out of the pot version)
4. Cover the models with a satin varnish (or floor polish as I do). Wait for it to dry well before continuing
5. Apply thin black wash with a large brush all over the models. Again be careful not to overdo it. The varnish layer will help the ink to spread neatly
6. At this point the models will be all red with nice shading. Paint all areas that shouldn't be red with layers of thinned black paint. Don't apply just normal thickness black paint. If you do layers of watered-down paint you will get neat gradients with minimal work
7. Finish the bases in colours contrasting to the Mephiston Red so that the models stand out. This will also make their almost uniform redness a statement to their otherworldliness rather than the painter just being efficient
And always remember to have fun! It's a hobby after all.
