Protection against corrosion is enhanced slightly, but the base metal characteristics may cause a blackened finish on steel to fail if not continuously maintained in an indoor environment.
Oxides produced by this alkali method are weak and prone to abrasion if not protected with waxes or oils. This process can develop a deep black oxide over the surface of the steel. One such method to achieve these tones is by dipping it in a heated chemical bath. Oscura Blackened Steel can be blackened or given colors ranging from dark brown to black.

Posted about my SAB listing a few weeks ago about not showing up in search only when you entered the exact name.
3) I always spray on a mat polyurethane top coat or two for a smooth finish and the finished piece looks completely natural. Even on the perfectly flat surface it didnt leave brush marks.
