There wasn't much to do for the forward cargo side walls. I match drilled the holes, deburred primed and installed the platenuts. Then I decided I wouldn't be putting this on anytime soon so I painted it with my interior paint.
I'm using the Rustoleum Hammered Look, Lt. Grey. I like the finish.
I think all the covers and parts that are removable should get interior paint and set aside. So that is what I'll be doing from here forward.
