Hammerite Kurust Rust Converter

Kurust turns firmly bonded surface rust into a stable black layer that can be painted over, instead of grinding back to bright metal. Brush it onto the rust, let it react and darken, then overcoat once it has dried for the time printed on the bottle.

Loose scale and flaking rust must come off first: it converts rust that is stuck to the steel, not rust that is falling off. 90 ml and 250 ml.
