Here I show you a quick video about how to paint weathering effects on your miniatures.
This is valid for any armor or vehicle of Warhammer 40.000 or any other wargame.
Here are the steps explained in the video:
1.- Paint the shoulder pad / miniature using the colors you prefer.
2.- Create some chipping, use a sponge or brush and your lightest highlight color. Then use a dark brown color over the previous chips.
3.- Use oil paints to create some streaking effects. I have used AMMO Rust oilbrusher because it makes the process easier, but you can use any oil paint. Apply it and wait 1-2 minutes. After that use white spirit to blur it and its done!
