Ok, most of my pieces (front fenders, doors, hood, etc) have epoxy primer on them and I have pretty much finished phase 1 of the body filler.. what's next? do I get a hose and spray off all of the dust and then spray my first coat of primer on them and then go back and do more body filler or what? What's the next couple of things that I need to do so I can keep the ball rolling? Thanks!
