I've been using Clenzoil on the metal for a long time, and when I get done with the wipedown, I usually wipe the stock down with the same cloth. Clenzoil has been promoted (sort of like Ballistol)as a general purpose firearms care product, and it seems to work pretty well. I have used Howards Feed and Wax too, but on the factory synthetic finish, it's mostly useful for the wax. The Kimber has got a few small dings, but I try to be careful and not beat it up.
