How would the factory have achieved the line? Surely they didn't have a guy in there taping the line.
I don't know the answer , maybe some sort of template? From what I've seen it looks like where the paint stopped at the transition / wrap is not a sharp , perfect line but more of a soft almost like the end of a paint pattern . Maybe one of the other members has a better explanation. What I did was attempt to duplicate what I'd observed.
