Suitable for protecting ferrous metals in humid conditions, this clear coating will give long lasting protection against rust and corrosion on metal components in both external and internal environments. It forms a continuous homogenous film that will not stain or mark components. The film will resist acid from the skin and so allows for subsequent handling. As it will also remove surface moisture on application it is suitable as an anti-seize coating on bolts, hinges, fixings or any moving part. Having been testing for over 250 hours in salt spray tests, it is great for use on a boat.
