Cerakote won't hold up to constant rubbing for to long if your not using a rifle holder of some sort. I have several cerakoted rifles that have rubbed down to bare metal from riding in the truck. Mostly on the end of the brake and along the ridges of the flutes. I will say I'm hard on hunting rifles and rarely use a case.
I am also hard on this one. It never sees the inside of the house unless I clean the bore. It is like a tool that you carry with you all the time. Thanks for the information on the cerakote. If it rubs off then I am no better off than I am now. Will have to start greasing it up more.
