In real life, one fender arch was started and finished before the other side got cut. But in these pictures, I'll be swapping back and forth. The passenger side was first done (the last 4 pics), and as you could see, much of that fender was bare steel, and the marks do not show up well in the pictures. The driver fender was in gray primer, and the markers show up a lot better. These 4 pic are the driver side so you can see the marks better. I'll be swapping side to side because some pictures are easier to see what is going on, but understand the entire process was the same for both sides. Got lots of pictures to post.
