I've watched that video before. He's kinda cheating with two sprayers and the car disassembled. I've read many times about trying to keep a wet edge so I am a little paranoid about it. Like when you paint the top of a car that you can't completely reach across like mine, what is the right way? In this video he is able to reach all the way across the car and get to the other side so it isn't an issue.
