Dirty Down Yellow Rust

25ml Apply yellow rust paint in the same way as our normal rust paint, by brush or airbrush/sprayer. Use on its own or with normal rust effect paint. A single coat of yellow rust is light yellow shade but the shade darkens as more coats are applied. If several coats are applied the colour darkens to a shade similar to that of our normal rust effect paint. Mix with our normal rust paint to create different shades of rust..
