It's kinda hard to teach somebody to paint. It's not hard to do at all but, you kinda need to just put some paint in a spray gun and go make runs and dry spots. Learn from your mistakes. In time you will learn what works for you. In the end the hardest part is the prep work. As an example, it takes me 2-3 days to get an RV ready for primer but only 30 minutes to spray it.
