My process, that so far, seems to have done the trick, since the rust was NOT THAT bad, but it did look like it was sitting at the bottom of a lake. It now looks almost perfect. I just need to get out to the range with ym buddy and have him shoot 10 rounds.
Step 1: Wire Brush used DRY!! (like you were cleaning battery contacts that corroded or whatnot, that way, the rust dust does not STICK to the abrrle like when wet.) You MUST BLOW IT OUT after going up and down, like you would clean normally)
Step 2 (Optional, I did not do it, but I suppose you could): WD40... don't laugh, and DON'T say that this stuff corrodes. It can clean just about anything, and it dissolves everything. Trust me, it works. It will dissolve any hardened gunk. I know, because I used it on my 1911 compensator, when the powder blast gunked up in the ports on the comp...looks new now). Just remember to clean WELLLLL with patches afterward. Makes sure they come out clean and dry. Then you MUST proceed to step 3 if you do this.

Step 3 (or 2 if you bailed on step Optional - WD40): LUBE IT UP! (don't use spit... LOL.. yea that's a #### reference). Make sure you lube it over the top! That way, no more rust wil develop, since it has been inhibited.
Step 4: SHOOT! Make sure to go to the range and blast about 10 + rounds down the barrel. The high heat, high pressure, and the tight fit of the bullet down the barrel (not a #### reference, I swear), will act as a brush and take out the rest. This was a recommendation by a) a fellow CGNer (not sure if they care to be named, they can do this out of their own will if so desired) and b) my father.
(YES I thought this last pic was quite funny, sorry if that offends anyone.. but its funny, ok? lol)
