It was an ok class, I took it 3 years ago...maybe 4. Good experience, good trip but I learned more about 'Buy my products' and 'MY Equipment' etc. Good tips on applying stencils and such, but to be honest- I like Cerakote's training better and use their products more- if you are looking for a pretty honest answer as I am factory certified in both.
IMO Dura Coat is great for 'coloring' and making patterns on already finished rifles, but Cerakote works great as all of that AND is a standalone finish.
The MAIN thing is to go to the Leinenkugel brewery!
