Going through the steps like a preprogrammed robot is not the point. Use common sense - If there is too much material, you sand. If there is not enough material, you add some.
You dont sand before putting on bondo. Sand after bondo or what ever putty you are using.
A good rule of thumb my father told me is when you think you are done sanding, sand some more. You want a smooth uniformed surface no lumps, cracks, holes, ect. You also have to work your way from a high grit paper to a low one. I go from 80 to 100 to 220 to 320. By the time im done its as smooth as glass.
