Since I posted up pics of my Khador Warjacks, a few people have asked how I did the Gritty/weathered look on the armour.
So here's my quick step by step of Foam Weathering.
What you'll need
A brush for mixing paints, a dry brush/old brush and some foam. For foam I use one of the off cuts from my carry case, but foam from a blister pack will work just as well.
Step 1 - Basecoat
Paint all the basecoat on the model and all the layering you might need to do. Bear in mind, this will messy and you will have to re-paint some areas.
Step 2 - Paints & Mixing
I mixed GW's Scorched Brown, Chaos Black and Knarloc Green (because this the base colour i'm painting over)
Now dip the foam into the paint. And dabbing the foam should give you the effect below.
Step 3 - Dabbing the 1st colour
Dap the area's you want to look worn.
Should look like this when finished.
This also works the same on the Red area's but show up more on brighter colours.
I used the Dry/Old Brush to prod in the hard to reach areas.
Step 4 - Metal Chips
Do the same, but this time with Bolt Gun Metal
Should look like this.
Step 5 - Fixing up
If you've done to much, you can go back and dab some of the original base coat colour over the top (this case it Knarloc Green).
Re-paint the area's which shouldn't be worn.
Step 6 - Wash
Once you're happy with it, given the model a coat of Delvan Mud wash.
Once done, carry on with Highlighting and Shading as normal.
Hope this is useful.
I've finished this unit now, so in a few days I'll post up the finished pictures.
