I've got an unfinished Estes Saturn V 25th anniversary with paper wraps. I looked at it while ago and the wraps look really good. It looks like I used Elmer's white glue on it as there is no yellowing at the edge of the wraps that would show with yellow glue, nor brown from contact cement. That means one of three things were different from the LJ-II application.

1. White glue might not have caused bubbling (didn't soak in and soften paper like yellow did?)
2. Estes paper wraps may be different allowing easier application
3. I have lost a lot of skills over the years since I started the Saturn...

Maybe a combination...
