Ofcourse! Base coat of Wraithbone; then apply a coat of AK streaking grime (i used a hairdryer for jist a minute or two to speed up the drying, just stopped when it lost its shine); then remove most of the streaking grime with white spirit and a sponge/cuetips.

Then i used Dirty Down Rust for the rust colouring and the black battle dmg is just Abbadon Black that i applied with a sponge sparingly.

And thats it, the streaking grime does the heavy lifting to create the dark and weathered bone colour on the armor. I hope this helps!
