Hi, I had to remove some Dicor to replace the wind sensor for the awing. I found that spraying it with Extreme Simple Green precision aircraft cleaner diluted 1:3 and keeping it soaked acted as a releasing agent so that the Dicor would not stick back on itself or any of the tools or blades used. You could cut the Dicor with a razor blade with relative ease. Although it did not dissolve the Dicor, it made it substantially easier to remove.
Just a thought.
