No. You sand carefully, and then you look for scratches. And if there are any (there always are), you go back down one grit and after that, try it again. If the scratches are still there, you have to go down two grit, and then work your way back up. And the scratches you're looking for are very tiny.

I'm going to be leaving some of them in (because I just can't seem to get rid of them all), and hope that after the final sanding, the marks will come out when I buff it.
