Chaos knights are the fast moving, heavily armoured troops of the miniature war-gaming system, Warhammer. A Chaos army is full of brutal warriors, seeking the blessing of their brutal dark gods on the battlefield, and the knights are the "brutal force" of the army. Painting Chaos knights can be a really fun activity, as you can let your imagination run wild to create an imposing army that strikes fear into the heart of the enemy.
File away any moulding lines on the figure with a metal file, available from craft shops. You can use sandpaper but it is not ideal, especially for metal figures.
Assemble the figure using superglue, and allow this to dry thoroughly before proceeding to step three. If the Chaos knight is mounted, it is much easier to leave horse and rider separated until after they are painted, to allow you to reach places you won't be able to if they are assembled first. Also paint shields before assembly for the same reason.
Fill in any gaps with modelling putty. Warm it in your hands first so it is easy to work with, and then push it into the gaps on the figure. Smooth the putty flush with the figure while it is still warm, then allow it to dry and harden. You may need to very gently file the putty after it has hardened, to make sure it is smooth for painting.
Apply a black undercoat to the figure, and allow to dry before painting.
Paint the armoured areas of the figure with a rusty colour like Warhammer's "Tin Bitz." For leather areas, choose a brown paint like "Scorched Brown." For any other metal areas like chainmail and sword blades, use the colour "Chainmail," and for bone use "Scorched Brown" again. For any cloth areas, choose whatever colour you would like to represent your army. Allow to dry.
Mix a brown paint with water to create a brown "wash." This very watery, runny paint should then be applied all over the figure with a large brush. This "wash" method gives the figure the detail of shadow, as the watery paint gathers naturally in creases. Allow to dry.
Highlight detail on the figure by "dry brushing." Apply a small amount of paint to a dry brush, and then remove most of this paint from the brush on to a piece of paper towel. When most of the paint has been removed, apply what is left to the figure using very quick, light strokes. Choose one area at a time, the armour for example, and choose a similar colour but in a lighter shade for the dry brushing. Repeat this for all the other areas such as fur, bone, and cloth.
Applying a varnish will help to protect your figures after they have been painted.
