This is a 25ml bottle of Dirty Down Rust Effect Paint.

With Dirty Down Rust Effect Paint you can simulate a punctual, natural rust effect on props, model tanks, model trains, track edge sections, cars or trucks and miniatures. 
With this treatment you will get a natural rusty colour but not the rough surface of normal rust.
Dirty Down Rust Effect Paint simulates rust on styrofoam, plastic, metal, casting resin and even paper.
