To show my OCD (obsessive compulsive disorder) in all of its glory... I never trusted my eyes, nor the panels to make sure alignment was true all the way around the car. Plus my floor has a slope in it due to a central drain in the shops floor (so a person can not take measurements from the floor up, due to its irregularity)
SO... I constantly checked everything with stringers.
In-fact, I even would take pictures and use my computer to make sure everything was aligning properly.
This would show me what needs to be tweaked, and what needs to stay put!
