Dr. Zooch Saturn V Build Step 11 Fit and Gluing Details Part 3

Here's how the 5" long S-IC tunnel sits over the wraps and black areas.
It will have to be painted black where it covers the black vertical strips.

I used Scotch tape for the masks.
A small mask was set over the upper, smaller black tip area.

The tunnel was set on the body and the lower tape mask set in place.
This assures the lower mask will be in line with the bottom of the card stock wrap where the black color stops.

The inset picture shows the tunnels ready for the black paint.

I got a clean mask is using just clear Scotch tape.
