When I did my first two As, I used acrylic lacquer and one-part Feather Fill.

Was just trying to get the latest, easiest way..

If you want a good surface and adhesion to last you want something with a hardener/catalyst, period. I would never use a one part of anything...primer, paint, anything.
If you're trying to save money, PPG's shop line 202 2k primer will work. It shrinks a little but blocks out nice. You just need to give it a few days to cure propery before final blocking to prevent anything showing up in your basecoat.
