I've done some Armor Black for Larry, on his wife's pistol. It's damn nice. On the bake-on Cerakote (H-Series), you control what it looks like, based on the amount of hardener you use when mixing it. You can mix it super-flat, or shiny, depending on that. On Cerakote C-Series, air-dry, you get what it is, but you pick it when you buy it. You want flat? They'll have it. Bake on with the H-Series, and determine your own, that's my opinion. H-Series is more abrasion resistant. C-Series is more heat resistant. C-Series for barrels, suppressors, car headers, etc... H-Series for everything else...
