I used the Dremel tool with circular cutoff disk to make a couple of slices in the fiberglass fairing skirt on the canopy. Then I carefully wedged toothpicks under the fiberglass to get it to part from the canopy frame and plexiglass. The epoxy does not form a chemical bond to aluminum, so I was able to break the mechanical bond with some effort. This is why it is so important to do a good job of roughing up the aluminum and plexiglass before laying up the skirt.
The skirt cleanly came off in 1 large piece after applying tooth pick wedges under it. Here you can see the glass bead/resin fillet and fiberglass layers and the underlying rough aluminum skin and plexiglass. You can also see the aluminum clips that hold down the edge of the plexiglass.
