Dr. Zooch Saturn V Build Step 11 Fit and Gluing Details Part 2

The upper and lower long cable tunnels were notched to fit over the wraps.

Set the tunnel over the body and mark where it intersects the wrap edge.
The square edge of the notch was cut with a razor blade and the rest sanded off with 200 grit on a block.
This notch area is not deep, cut a little at a time and check often as you trim and sand it away.

Before gluing on the tunnels, some of the paint  was scratched off for a better bond.

Don't scratch an area too wide. Keep it narrower than the tunnel width.
