This may not be what you want, but I know of several folks that have done colored bedliner in place of paint..
You can get about any color and texture, and it has a flat look to it...I've done bedliner, molding down on both the blazer hunting trucks I have,,,,holds up very well and cleans easy...and those trucks take a beating..I've seen some all over jobs that look pretty good...sucks if you ever want to paint it though..
I even sprayed the inside of my alum boat and did a all over on my buddies duck boat in natgear camo
Whatever you decide on, be sure to get some epoxy on that bare metal..
