Unsurpassed. No other word can adequately describe Cerakote™ Glacier Green C-8100. Formulated to withstand internal exhaust gas temperatures of up to 1,800° Fahrenheit and thermal shock from those temperatures directly into water with no adverse effects. C-8100 retains its bright green, sleek satin finish in the most extreme environments. Cerakote™ Glacier Series coatings are a line of air cured, ready-to-spray ceramic coatings.
