I have not been certified. My family had a Ford/Lincoln Dealership for over 70 years, I grew up in it, and had tons of painting experience. Cerakote is not exactly the same, but the principals still apply. Good prep is number one and proper technique when spraying is equally important. I have seen some absolute garbage from well known applicators, and some stellar work by others. I learned it real quick, and have no problems. I will tell you that you don’t want to learn on the metallic colors if you want an immediate smooth finish to judge your own work. The solids like Graphite Black, FDE, Sniper Green are great to get good at first.
And- that work at shot show was in fact really nice. I don’t do artistic and multi layer things, but the finish on my parts compared to what I saw at Shot was comparable. I say get set up and learn!
