Those test scraps have been long since recycled. I don't have a camera with a good battery to make a new one anyway.
The finish is enamel on aluminum on the plastic substrate. It's reported to be as stiff as 5/8" plywood. I doubt I could dent it with a hammer.
The edge detail would work as well in sheet metal. A good next experiment would be to make a curved rather than straight edge. That would require an edge/bead roller rather than the straight roller I used.
