Cerakote is a lot more permanent. A lot better of a finish, protection wise against rust and durability. But it isn't as easy to apply as Duracoat. If you're just wanting to change the color, I'd say go with an easy Duracoat. If you want a lifetime finish and protection, spring for the cerakote. I'm currently getting set up to apply Cerakote, and know a guy that does great work with it too. Depending on your location in Utah, I may be able to help.
