Will Rust Bullet protect metal from magnesium chloride?

Yes. Rust Bullet will perform well to protect metal from direct contact with magnesium chloride. Magnesium chloride is used as a de-icer on roads in many states. It is very corrosive will cause significant damage to concrete and metal. It will affect substrates in two ways, either by a slow rate or a fast attack depending on the concentration and the conditions and circumstances. A very high concentration of magnesium chloride on a frequent basis will reduce the protective properties of any corrosion control coating, including Rust Bullet. Rust Bullet with its armor tuff coating will last longer and provide better protection than any other product available. A dry film thickness (dft) of 12 -15 mils is recommended for surface that will come into contact with magnesium chloride. Regular inspection of the surface to identify any breaches in the coating for immediate and easy repair is always recommended.
