Since you mentioned "NO STEP," I feel compelled to add my opinion. The "NO STEP" markings have two primary purposes: 1.) fall prevention; and 2.) preventing damage to fragile wing surfaces from tool boxes, etc. being set on them. As for fall prevention, if the moveable surface does not have hydraulic pressure, then the part may give way if stepped on. I'm not so sure the VF-0 and later variable fighters rely on (only?) hydraulics to keep wing surfaces firm. Also, there are recent modern fighter plane examples that have done away with the "NO STEP" markings altogether.
As far as damage to wing surface prevention, it's very difficult for me to see the VF-0 and later variable fighter wings being fragile. Going through the Macross timeline, from as early as Macross Zero, we see the VF-0 get thrown onto the wings (see Macross Zero, second episode) with no damage to the wings. Additionally, we get to see aerial manuevers that would arguably rip wings made from conventionall materials apart. Consequently, I think (tedious) application of the "NO STEP" markings goes more to looking realistic than being realistic, so save yourself some time (unless you really like the look of these markings). For those totally not interested in this, please forgive the ramblings of a drunk.
