Once the lines are drawn on the fuse side marking both wing and stab incidences, a layer of clear mylar is ironed on to protect the lines. Magic marker doesn't survive the sun long term so I hope to have the thing fully wrung out by the time they fade away. With firewall at 90 degrees (no downthrust), the tail needed to be raised 1/16" from my bench, hence the misalignment on the front stab locator. No biggie......
