Polishing an AG barrel ??

Do or don´t ?? Well – i do but then again i´m a bit weird in that regard : When someone says “Don´t” i most definitely do .
Anyways – i like to polish my firearm barrels every now and then and i´ve NEVER – not once – had any negative side effects of that. There´s this old wifes tale saying you shouldn´t polish an AG barrel since “those barrels are made of mild steel” and will wear out fast. Bullshit i say !
Why should an LW barrel made for AG – or any other marquee barrel – be of a inferior or so soft material it wouldn´t handle the “rigors” of polishin if needed. Anyone with a good,educated,non-theorical answer to this age old question ?? I just had an arguement with one Mr. Know-It-All (no,not Dr. Evil) about the subject. That dumbass says it´s the worse thing i could do to my barrel…

P.S I´ve just finished the Cricket barrel polish (after the first 700 or so rounds and it was SHITTY) and i bet once “seasoned” it´ll shoot at least as good as before the no-no – if not better. And it´ll take a bit longer time before it gets all leaded up again. And it´ll be a bit easier to clean for a good while until it needs to be polished again.
