Yeah, or you can take classes...
classes will only teach you what you can read online or in articles.. painting is a skill, not a theory.. i went to school for 2 years for automotive collison and refinishing, and i learned more in the first few months in a shop then i did there.. it is learned by hands on experience.. learning from mistakes and things that work out the way you want them to. i could tell you exactly how to do a quality paint job step by step, it doesn't mean you will do it perfect the first time.. practice makes perfect ring a bell?
