is it a strict requirment or can you get away with an unannodized lower/upper on an 80% build.

Nothing is a strict requirement, anodizing prevents corrosion, nothing more. So does paint.

I normally just paint or clear coat my in the white receivers.

All of my 80% receivers I paint myself (I used to use Cerakote, but now Durabake). It works great.

I have gotten to the point that even the commercial receivers that I purchase at the gunstore, I sand blast off the anodizing, and then durabake it.
It looks much nicer.

Well, Type 3 anodizing makes the aluminum surface harder, increasing the wear resistance.

The only place that comes into play in the lower is in the hammer pin hole.  The hammer pin normally rotates with the hammer and it loaded fairly heavily during cocking.  An un-anodized lower hammer pin hole will eventually egg-out.  That is why I would recommend anti-rotation pins for an un-anodized lower

My first billet 80%'er is about 3 years old and has well over 3k rounds through it.  Still unanodized and shows very little sign of wear even on the cnc exterior tooling marks.
