It isn’t that simple. You have to build a finish, with each coat melted into the previous coat, thick enough to sand level, with progressive sanding grits, prior to buffing. It’s this level base of finish, that allows you to achieve a mirror and high gloss finish with a buffer. If you use the wrong finish, you can buff through layers of finish that are not melted into the previous coat which will show witness lines of buffing through individual coats.
Plus what runamuck says is very true.
