only pipes I've ever wrapped were overhead parking structure clearance bars, but my trick was just to accept that no one would ever see the top of it

i still took precautions, and marked center of my graphic and pre-slit the material to ride that line and started at the bottom of the pipe as square as possible and did each side separately, using my 1"slit as my hinge, and then overlapped on top with zero regard for pixel alignment.
