About the product only a few words are losing: brush rust from the object with a wire brush, apply rust primer with a brush. Allow to dry for a day. Black colored points are then converted into a stable mass - gray spots are easily treated again with primer rust until they have also blackened. As the product is different in any way from the much more expensive competitors. In a word: The quality fits, I am happy and will buy the product again! Perhaps even a note to "childproof" packaging: Yes, the closure can be actually incredibly difficult to open. The screw cap is firmly closed on delivery that the safety cap over it just spins. Here I can only offer you a trick: The black protective cap using a screwdriver to pry up. Then comes including the blue screw cap to the fore. The can then (I've taken this a pipe wrench to help) turn up with some force. And since I have no children in the household, which could keep the corrosive liquid for raspberry juice (the color actually looks very much like a children's drink!), I did not put the safety cap after use to the cannister. In a household with small children but you should really lock away the product - the "raspberry juice-like" color would probably really a moment of danger for children! Conclusion: A product that can do much more on the quality than suggesting be more favorable price ...
