Vallejo Special FX Galvanic Corrosion (18ml)

Bare metal never stays shiny for long out in the field, and Galvanic Corrosion is how you tell that story. Brush it over exposed steel, rivets and panel lines to build up the grimy, electrolytic staining you get where metal has been arguing with the weather. It's a ready-to-use effect, so there's no mixing and no guesswork — load a brush and start ageing your models straight away.

At a glance

Best for

• Rust, oxidisation and battle damage on tanks, vehicles and armour
• Grimy sci-fi and post-apocalyptic bases and terrain
• Layering with other Special FX effects for real depth

A little goes a long way — work it into recesses and let it settle where water would naturally sit for the most convincing corrosion.

Ready-to-use weathering, no mixing required. Pairs perfectly with the rest of the Vallejo Special FX range and a scruffy old brush kept just for weathering.
