I went with Grey to match my side rails.
My installer removed the inner tailgate panel before spraying the rhino-lining and re-attached it afterward. That way, you'll be able to get into the tailgate innards, if needed. I asked him to remove the bed-bolts before he sprayed but was afraid of mis-aligning the bed when he was climbing in and out during the procedure.
Good luck.
