Dr. Zooch Saturn V Build Step 9 The Mask & Reveal

With the rear wrap taped in place, the black areas were extended down the body tube using a pencil and aluminum angle.
These lines will only go a little over an inch above the top of the wrap edge.

I went back and double checked the width of the vertical strips.

A piece of paper was marked and all four widths were checked. One black area had to be adjusted.

I used my standard Scotch tape mask.
The tape was set on a window glass, marked with a wide Sharpie pen and a new clean edge cut.
These tape strips were set down the pencil lines.

Here the Scotch tape masks are being lifted showing the mask.

The cardstock wrap print is held against the black masked area.

The match next to the lower printed black widths are good.
