No problems so far with any of my double cut blades. I do tend to keep them clean. After I use one, I'll wash it with hot soapy water, dry it off, and then put on some Tuff-Glide or some CLP and let that soak in (into the bead blast) for a bit before I wipe it down and sheath it.
Folks often worry about the parkerized finish on some guns, the Remington 870 Express being an example. However, in my mind, those tiny little nooks and crannies in the metal actually hold onto CLP better than a blued gun/barrel. You just have to take the time to do some very basic maintenance before you put up the gun.
