This ceramic and polymer coating specifically enhances a number of physical performance properties including abrasion/wear resistance, corrosion resistance, chemical resistance, impact strength, and hardness. After making the tests, Cerakote is seventy times better than chrome and even a hundred times better than black zinc.
