I was asked a few times on how I did the battle damage on my Imperial Fists.
It is a variation on the sponge method using a different tool.
I love the look of sponge painted battle damage, but using a sponge on a mini tends to end up being overkill.
I am on the lookout for a tool that will do a similar job but on a smaller scale.
Right now I am tring out this sculpting tool I found in a package of cheap clay scuplting tools.
It looks like a cross between a toolbrush and a pipe cleaner(Which I want to try out if I can find one).
The tool has many small nylon threads that seem to do a good job of making sparse random patterns.
Now on the the method
For lighter colored armors(White/Yellow/Orange)
I use a mix of Charadon Granite and Dark Flesh(3:1)
For darker colors I use a Mix of the Basecoat and Charadon Granite(3:1)
The I use the tool to make a FEW and I cannot stress a few marks on the armor.
If you go overboard it will look like camouflage.
I put a few marks on the greaves,Boot-tips,and a random mark or two on a shoulder pad and arm.
I also make sure the top rear portion has a few scratches where he would be ducking under rubble and some of it snagging his pack.
Then I carefully highlight underneath each scratch with Bleached Bone.
The highlight should not be the same size as the scratch and sometimes only a pinprick dot of highlight is all you need.
On one or two of my larger chips I will paint a tiny hint of boltgun metal in the middle.
