Why am I thinking this way? Well, the bends are rather tight at the corners, and it looked like it might be tough to roll that edge over in that configuration. Then again, it could merely be congenital idiocy on my part 
The part in question is the short cowling that surrounds the seat back, as seen in the picture here. What say experts?

Assuming for lack of specifics, that your metal is 3003 .040 and your wire diameter is 5/32, then I would wire it first and then bend it around.
Note: I have made very tightly-radiused wire edges using .050 3003 and 3/16 wire - around 1.5inch dia corners, but I had to hot work the wire and fight the sheet to wrap it nicely ....
By contrast, yours is nice and easy.
