Forget that! Vinegar and a scotch bright pad will remove the finish. After that get some mother's mag polish and buff that sucker out. Clean rag or t shirt cut up and apply the polish, rub it in until you start to get black. Then take another clean rag and wipe it off. Do that in front of the tv for like an hour and it'll be nice and shiny! Just did it to the barrel on my lc9.
If you've got one foot in yesterday, and the other in tomorrow, than you're pissing on today.
