When Games Workshop released Cities of Death, they released a set of resin Urban Barricades and Walls. Unlike the Urban Basing Kit it is still available at the time of writing. You got six barricades and they blended in nicely with the plastic ruins which were also released with Cities of Death.
First was a black undercoat. I gave the barricades a Codex Grey drybrush, this was quite a heavy drybrush.
The next stage was to paint and drybrush certain areas.
I painted the broken eagle with Burnished Gold. Painted the walls a grey and highlighted some details with Boltgun Metal.
The earth sections were drybrushed with Scorched Brown.
