I enjoy working spectraply. Periodically soaking it in thin CA, as it turns down, minimizes the fuzzing effect mentioned above and reduces any tendency for the plys to chunk off or separate from one another.
Perhaps STBO here, but a word of caution about this technique. Protect your eyes and breathing. The fumes from large amounts of CA can be especially irritating and not particularly heatlthy. I wear a respirator, goggles and have a large fan aimed so as to blow the fumes away from my face.
Good luck!
