After masking the root edges of all the fins, a paper cover was made to entirely cover the fin sides.
In the back of the BT-101 tube, rolled paper was taped to the inside to keep out the black paint.
I did my best to cover the rest of the fairings that will remain white.
Maybe I should have used that expensive tape!
All the lines masked with Scotch tape came out clean.
The masking tape results were just okay.
Enlarge the picture to see the masked edges over the vacuformed wrap. All are repairable.
Here the Scotch tape mask is pulled off from the fin root edges. The Scotch tape lines were clean.
