A couple of days ago I asked everyone for suggestions on how to paint rusty effects on bulkheads etc. Thanks for all of your suggestions, and it did help me a lot.
Firstly I undercoated black and then sprayed it Mournefang Brown. I then drybrushed dryad bark over it sporadically (yes it is darker, the reason why is because I want some orange in the recesses).
I then dipped my little finger in dark iron weathering pigment and brushed it all over. I then did a little drybrush of the powder too for the hard to reach places.
I then used orange rust and old rust weathering powders across the piece.
I then drybrushed it again to even it out.
Followed by a little bit more dark iron weathering powder.
I'm quite happy with how it has turned out. I will be using the technique on a few more barricades, but I will also be using the hairspray (with sugar here and there too possibly), airbrush a colour, scratch off and oil wash streaks technique on them too possibly.
