Would it be good for coating the bare aluminum after milling an 80% lower?

I wouldn't use it. I use a heat black paint (like you would repaint a BBQ grill) heat the receiver spray at least 6 coats heating slightly between the coats then let set a week. Saturate in Brake Free CLP let set for 1 month then you have a factory coat that resist scratches. I use this method for all AK-47 metal parts as well. Just remember to use Brake Parts Cleaner on the metal before painting to clean any oil even fingerprints off the bare metal.

Can this be used to touch up black anodized aluminum? Will it harm the surrounding anodized areas?

Yes! I used this to touch up a black anodized Vortex riflescope. The results are the scope looks brand new! Make sure to clean surface thoroughly first. I used an alcohol swab, then dry wipe with paper towel, then paper towel with a bit of dawn to degrease, then dry paper towel. I then used a large cotton swab to apply. I held it on for 30 seconds at a time with one minute breaks in between, for no more than 5 total times per scuff. Good luck!

Will this darken gold anodized aluminum??

Has to be clean, bare aluminum.

Will this only oxidize bare aluminum? Stone washed purple knife scales and want to darken up the bare (silver) aluminum coming through.

I used this to try and touch up a bare spot on a mossberg 500 shotgun. It actually etched the bare areas, and stripped off part of the remaining bluing(black). BUT after contacting mossberg I was told that their allow, and finish is not compatable with aluminum black. In short I cannot answer you're question except to say call the maker for a hint first..
