Luso, isso dependerá do tipo de cerakote aplicado.
Cerakot C-Series should ONLY be used for high-temp applications up to 1700°, such as suppressors and machine gun barrels. C-Series is available in a wide range of colors to match the overall finish requirement of the firearm or weapons system. C-Series is used to coat scopes and other optics, as well as fiberglass, polymer and other substrates which cannot be thermally cured.
Cerakote H-Series is the most durable of the standard Cerakote™ product and provides the best performance in hardness, wear,scratch resistance, adhesion and rust resistance. It can withstand temperatures up to 400f degrees and comes in nearly 50 colors.H-Series is a thermal cure finish and therefore should not be applied to optics and other items or substrates which cannot be cured atthe required temperatures.
