Unsurpassed. No other word can adequately describe Cerakote™ Glacier Silver C-7700. Formulated to withstand internal exhaust gas temperatures up to 1,800° Fahrenheit and thermal shock from those temperatures directly into water with no adverse effects. C-7700 retains its bright silver, sleek satin finish in the most extreme environments. Cerakote™ Glacier Series coatings are a line of air cured, ready-to-spray ceramic coatings.
