The Black Magic finish develops a true conversion coating, converting iron to the naturally occurring black iron oxide compound called magnetite (Fe304). This conversion coating has a tight, adherent, highly durable composition, which does not easily scratch and does not chip, flake or peel. The coating produces an attractive black finish that imparts moderate corrosion resistance and yields a finish that when properly sealed, resists galling and enhances lubricity. Black Magic is a top performer that will last indefinitely as long as proper care and maintenance are performed.
