You can take all the clases you want but, it is really only going to teach you technique more than anything. I say this because once your actually doing it you will find things that work for you. You may run air pressure higher or lower than suggested or, you may reduce your clear when the product sheet doesn't tell you to do it but, uou find it lays down better. The tech sheets of the paint gives you the general way to apply the product but, its really in the technique in how you apply it. Lighting and your eyes are going to very important.
