I am on a project that has a gun vault, large safe door, built-in display cabinets with glass doors and a ton of storage cabinets. It is all done in walnut with a rubbed tung oil finish. My reccomendation for the flooring (concrete now) is a high quality tight weave wool carpet, low nap. What would, or what have you guys done? The firearms stored in this vault will be high end. I will be able to use any feedback to make a decision.Thanks, mtmuley
