Ouch! Not sure how that happens in 12 hours.

Just FYI just because it's "stainless steel" doesn't mean it's completely rust-proof. It's just rust resistant.

I bought a spare 9mm barrel for my Sig 40, wasn't too abrasive with it so it wasn't full polished (the coating was stubborn). I coat it with oil like any other barrel and I keep it in a plastic ziplock bag.

I think it'll just be higher maintenance but I too like the two-tone look, just haven't tried it.
