Rolling custom tubes over aluminum mandrels (~6ft long), using wet layup with perforated shrink tape.

I tested a 2ft section with several coats of release wax directly on the aluminum, then carbon directly over that. It did release after freezing the tube, but with a LOT of effort. I’m worried a 6ft section would be impossible to remove. It seems like wax is too “grippy” for tubes, especially after freezing.

Is there a better release agent for tubes?
