Is that the Clean Metal Primer? Or the Automobile Primer?
The former is oil based and takes a while to cure while the latter is lacquer based and dries very quickly.
From my perspective, the clean metal primer is about the same as flat paint. Anyway, because it takes a while to fully cure, it can be prone to clogging the sandpaper. I've only purchased and used it by accident (ie, due to my own ignorance  ).
But I've had excellent results with their automotive primers.
Doug...not that I've painted a rocket in forever...
