I feared Cerakote might be a little thick for already well-bedded rifles, but my suspicions haven't proven valid so far, in several rifles. All bedding compounds shrink a little bit as they cure. Some shrink more than others, but apparently it's just enough to accommodate a layer of Cerakote.

Is the barrel free-floated, or have some form of contact bedding?
