I think it's just painted, no bed liner applied. My Silverado looked the same before I put a bed liner in it. My guess is steel, though no way to tell, or to know if that's a production intent prototype or not. I remember seeing the Slate Truck in person and being told the one they had for demo had composite body panels for prototyping, and they were not indicative of the production intent polymer panels.The inside bed caught my attention. I'm wondering if that's a glossy bed mat, a spray, or a composite bed. It sure looks slippery and glossy. Kind of hoping the final product is matte rough finish. BTW, huge fan of composite beds here. They're strong and they don't dent or rust. The Santa Cruz had a composite bed, as does the Ridgeline.
