Joe, My experience has been, that after the Smooth Prime, comes the real priming and sanding. At least then, you can wet sand it. There is no way that you will have all the pin holes out of it after smooth prime, so now the real work begins.
The nice thing about having that layer of Smooth Prime on there is that, if you put on a grey primer, you quickly know when it is time to stop sanding, look for pin holes, fill them, prime, and start sanding all over again.
