What problems are being experienced to initiate the desire to polish the chamber?
According to constructor, a Nitrided chamber might become sticky and cause short stroking for a few shots, then the problem goes away, never to return. It seems much more logical to put 50-100 rounds through the barrel during the initial range session, clear whatever malfunctions occur, then go on with life.
Actually he said it can/will occur after some rounds go downrange but it didn't just "go away"......it had to be polished.
The cheapness of the barrel got the better of me I guess. It appears to be a decent barrel (got it yesterday). If you notice in the OP I mentioned that my only other nitrided barrel had some major issues during a carbine class, the bane of the early M16: a stuck spent cartridge. Beat-it-out-with-a-cleaning-rod type of failure. I seek to avoid a repeat of that, that's all. If I can do something prophylactic (but not ignorant like over-polishing it) then why not?

F**k China!
Constructor did say it may need to be polished after firing some rounds, but he mentioned Iosso, JB and Flitz. All those are much less abrasive and provide a smoother surface than the Flexhone.
But its your inexpensive barrel. Hope it works out and not wears out!

800 grit will not hurt the chamber unless you run it for 2-3 minutes at high speed. Nitride/Melonite treated chambers are hard enough you can't recut them with a carbide reamer, I can cut chrome out in a second.
The difference is you know you are just trying to polish/smooth things out a bit not trying to enlarge the chamber.

Patriotism means to stand by the country. It does not mean to stand by the President... - Theodore Roosevelt, Lincoln and Free Speech, Metropolitan Magazine, Volume 47, Number 6, May 1918.
Every Communist must grasp the truth. Political power grows out of the barrel of a gun. Our principle is that the Party commands the gun, and the gun must never be allowed to command the Party Mao Zedong, 6 November, 1938 - speech to the Communist Patry of China's sixth Central Committee
