Developed as a more environmentally friendly version of traditional gun blackening, blueing and parkerising, this cold oxide blackening kit will provide everything you need to blacken ferrous metals; mild steel fastenings and brackets. Oxide blackening increases the corrosion resistance of treated parts which can be maintained through regular application of our Sealer or through the use of the de watering oil.
