I think I am through with the interior sheet metal. I want to get it all done and painted before I start riveting up the exterior. I have decided to powder coat all of the interior sheet metal for several reasons. 1. I don't have room at this point to set up my paint booth 2. It is reasonably cost effective (polyurethane paint is expensive) 3. Someone else is doing it.
The downside is that it is difficult to repair.
I am still planning on shooting "Rhino Liner" on at least the floor boards and maybe a couple of other high wear areas.
