I recently experimented with some rusty barrels on a diorama and decided I would write a tutorial on it for a couple of reasons: One, so other people can create the same effect should they want to. Two, so I can look it up when I want to do so again in the future and can remember how it’s done.
Equipment: Typhus Corrosion, Skagg Brown, Jokero Orange, Leadbelcher, Agrax Earthshade, Nihilakh Oxide.
I have used a wall for this, but it would work well on pipes or anything that might get rusty!
Paint the entire surface with Typhus Corrosion – this will add the rusty texture which we need for the next steps.
Drybrush with Skagg brown – those texture areas will start to show up in this and the next steps.
Looking a bit corroded there.
Stipple on silver, or other metallic colour, to show fresh chips in the rust.
Use Agrax Earthshade to put in some darker areas where crud might run.
Use Nihilakh Oxide to add a bit of colour to the deeper parts – maybe these were made of copper and are now tarnished!
Finished! Simple way to make an effective rust pattern!
