I mean if the car is a complete shell, that's one thing. You're not gonna see a whole lot of flex.....ESPECIALLY if you put braces in the door openings.....and probably very little then. There's just no weight there. So if it's a shell on a rotisserie, I say have at it, but if it's assembled, I like doing it as I outlined above. As I said though, opinions vary and people have had success doing it differently.
