I have had my Kimber for about a year now.
It's a Kimber Pro CDP II
I carry it in cool weather and take it to the range to shoot a lot.
I have never seen even a spot of rust on it anywhere, and believe me it's hot here & it gets sweat on it when I'm at the range.
I just wipe iit down with a inexpensive gun cloth that I bought at a gun show. It shines like new after several hundred rounds down range w/o any jams or misfires.
Sorry your having trouble with yours, but I'm not having any trouble with mine.
