Let there be dust!

Found a great product, Modellers Pigment, Brown Earth. I am in the process of applying it liberally to my Rooikat.
As you can in the attached image of a test bed variant, the dust really sticks.
So, this is what I am trying to emulate with my build.

Thanks for watching.

That looks really great, Gavin @snowman
The pigment sticks by itself or do you need to create a sticky surface first?

@johnb & @anthonyricco, the powders do stick to a point but there are specialist agents you can use to adhere lumps or smeer like a wash. Do some research on pigments, really cool stuff.

Looking excellent, my friend @snowman!

What a beast, loving it Gavin @snowman.
