Developed as a more environmentally friendly version of traditional gun blackening, blueing and parkerising, this solution is used as a replacement blackener for one of our blackening kits. Oxide blackening increases the corrosion resistance on steel and iron parts. This can be maintained through regular application of our Sealer or through the use of oils and waxes.
