How to make PSAN ?

My understanding is that PSAN is made by introducing a small amount of Zinc Oxide into a batch of melted AN.

My friend makes AN motors with unstabilized AN, and as long as one doesn't store them too long, there's no noticable density change.

That's basically it. Not exactly a basement chemistry project, though it would be possible. Use standard AN or buy PSAN if the motors will be stored for more than a few days or will undergo temperature fluctuations.
