Excellent Product, Easy to use after a good shake and a quick stir. It is non-toxic and after a simple application the Rust turned Black as specified. A second coat for good luck and then repaint the under & Top coat. I imagine that this 500ml will cover a vast area should I need it to. It is just what I have been looking for to kill rust where it occurs.
