RE: SCALE PANEL LINES
Just for information, and perhaps education.
I covered the whole airframe with silk, for strength; then doped until the weave was filled, then applied scuffed chrome monokote panals per whatever scale 3 views I had at the time. I used a scotchbite pad, and applied the adjacent panels 90 degrees to the adjacent panel (as much as possiblle) to emphasize the individual panels.
