Estes Bullpup #7000, Build Highlights Part 4, Tube CCA & Primer/Filler
You can get a evenly spaced CA reinforcement line around the end of a body tube.
Apply with a Q-tip, use your middle finger around and on top of the tube edge for a depth guide.
Some forum posts have mentioned that CA glue could help prevent a zipper.
Kelvar is like a thin, steel cable. The CA'd tube ends might be a bit stronger, but a coat of super glue isn't going to stop Kevlar from cutting through a cardboard tube.
Primer / filler was sprayed on and sanded to surface.
On the left you can can see the "coke bottle" recess below the launch lug. That's the glue inside, right above the upper centering ring.
When the glue dries it can pull in the body tube.
Some of the gray primer was left in the tail cone mold line.
On the nose cone the few low spots remaining in the seams were filled in with the sanded primer.
