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...

It used to be called auto primer, now it's called "Gray Filler Primer", #720. It's lacquer based, as it recommends lacquer thinner to clean the nozzle. The stuff dries extremely fast, I can put on multiple costs just holding the rocket for a minute between coats. Can says ready for sanding in 30m, though I usually wait a day, just so I don't bring any stink into the house.
