I'm a certified cerakote applicator and have recently started messing with KG Gun Kote. Of the two I would recommend Gun Kote to the home DIY. It is much easier to apply.
Both should be done with a HVLP .8 tip gun, but an airbrush can be used. Dry coating is the worst enemy you face with an airbrush as they both should be put on in one wet coat from top to bottom on the part.
There is more info on my website and feel free to shoot me an email if you have any questions. I'm off to the intro forum now as this is my first but not last post I would assume.
