Eight Gun Finishes Tested — With Surprising Results
Eight (8) various finishes are tested, including Blueing, Cerakote, DuraCoat, FailZero, Ion Bond, KG Gun Kote, NiBX, and Phosphate (Parkerizing). Eight metal firearm components (each with a different finish) are placed into the salt chamber to see how long it takes for each finish to show initial signs of corrosion. To provide a baseline for comparison, a “naked” 416 stainless steel barrel was also placed inside the test chamber. The test was started, and for each coating, the time was recorded when corrosion started to appear. FYI, if you thought “stainless steel” can’t rust, think again. The stainless barrel sample (along with the blued metal sample) showed visible corrosion after just 24 hours!
