If I understand your suggestion correctly, the friction fit of the paper inside the tube is serving the masking function. Would I presume that you at least apply tape at the ends of the tube, to create a good seal? That sounds like a good combination to me: use the rolled paper to fill most of the length of the tube, and then just use a thing strip of tape at the ends to seal it off.
One final note: I used plain old blue tape here because none of it was intended to create sharp mask lines. Later on I'll break out the Tamiya tape.
Keeping in mind, that sharp mask lines aren't important here (this build) just a good snug fit of the paper inside the tube with enough tape to keep it that way, is all you need. The tape really doesn't have to run the length of the tube/pod. As long as the paper is blocking the paint from going on the inside surface. I read where someone uses wax paper rolled up and stuck inside launch lugs for the same reason. There was no tape involved at all. Just the wax paper with its nature to unravel, making for a somewhat snug fit inside the lug. This prevents paint from getting in there also.
Let me know if a detailed diagram is needed. I'd hate to confuse anyone with something so simple.....:duck:
