My wife's Model 60W is in need of some minor refinishing on the barrel. I know that Black Oxide Bluing is corrosive, especially to aluminum so the receiver should be removed from the barrel. I've heard horror stories about totally ruining a model 60 by trying to remove and replace the barrel. Is it as bad as I've heard or is R/R common enough that it shouldn't be a problem? The finish isn't so bad that I can't live with it, I just want it to look nice for my wife.
