It's certainly different. I think I like it?
I would be very hard pushed not to draw on some aircraft type panel lines if I were confronted by so much bare brushed ally.
That Norton that you posted up was really begging for some panel lines especially along the rounded leading edges of the lower fairing, which already look a little like wing leading edges.
It would create the effect of the body work being made up like the skin of an aircraft with different panels forming the shape over ribs and frames....I think it would be cool.
You could also give the effect of lines of flush rivets along some of the panel lines. Perhaps with an appropriatly sized hollow punch pressed onto the surface and gently rotated to scribe a small circle?....A few air brushed shadows here and there....I can see it...
