Riveting F704 C/D to F704 and I tilted a little and marked the vertical support (F704 C/D) web. I hit it with a little scothbrite and I plan to drop a little primer in there.
I normally would just make sure there were no sharp edges and move on but this being part of the heart of the structure of the airplane, I thought I'd ask the brain trust what you think about this.
You can probably tell this is about .001" deep.
