I've found that all the info in the world will only do good if you have time with your spray equipment. You can tell a guy how to paint and prep a car till your blue in the face but untill he pulls the trigger its all just book smarts. Practice with your gun on test panels,old junkers,anything before you try to paint your car. Every paint line has its own attitude for lack of a better word. polyesters,urethanes, acrylics, lacquers all have spray different and have different mix ratios so there is only one way to learn and that’s to practice.
