Lots of YouTube videos on anodizing. Not hard compared to turning an 80 into a built lower. Just all sciencey and unknown like building an upper until you do it.
Hard anodizing is just a thicker layer. Anodizing is self limiting as it doesn't conduct.
Type3 hardcoat is twice or more thick than type2 and requires different procedures. https://www.caswellplating.com/anodi...ng-system.html

Hard-coat anodizing has extremely fine aluminum oxide powder (pulverized grinding wheel material) in the solution. IIRC , The particles take a charge and 'arc' themselves to the base metal. Makes for a Rockwell 70c hard skin. A high-speed toolbit is 65c. I've done parts and they would spark when a toolbit or drill would

What about powdercoating a finished lower? Would that clog up the threads?

Powder coating is too thick could cause a lot of issues.

So my question is what kind of strengthening can be expected from this coating when done to a non-anodized receiver interior?
Specifically as it relates to the stress points below the pin.

That's what I thought.
One step I did not consider in my first 80% build was treating the milled-out portion.
Bluing might be another option, right?

The gent in the video that I posted earlier did in fact have a RAW lower(no anodizing). I'm in the camp that believes anodizing does not strengthen the lower.
Here is his follow up video 2 years later.
