Citadel Technical Paint: Nihilakh Oxide (12ml)

Great for aging copper or bronze.

Great color. Used to make copper items appear rusty and weathered. Combine with a little blue wash to bring out some deep details. (experiment first, some models look better with different accents)

Finally the right paints for rust layering and no more mixing

Maybe it's purpose is a little too niche for me

I haven't used this much, yet, though I really like the effect it gives. I put it on with a dry brush, and can build up streaks of 'tarnish' that look pretty realistic as an effect.

This perfectly and easily reproduces the look of verdigris on weathered bronze, brass, or copper. It has become a must-have in my painting toolkit.

If you need some brass rust/patina for your figures you could do way worse than picking up this oxide paint.

This tech paint is pretty much what it's name depicts. When stippled on top of your shade coat, it creates an extremely realistic looking rust effect.

I love how this turns my regular minis into statues!! It's awesome!!!

I picked up the Oxide Technical Paint for doing metal interior base look and it does provide light blue with a hint of green look of old metal panels. The product needs to be shaken well but is still thin which works so might not want to put too many layers on as it sinks into cracks rather than staying on the surface (I am finding that a thin layer does stay on the top of gratings without sinking). Combined with a Black/Brown ink (Agrax Earthshade for example) and with a rust color, the overall look is very good, but without that ink it does seem too bright and too much like a light blue paint thinned down.
