At work we maintain everything from sno cats, TTs, and even electric vehicles, GEM, last week, I had to replace a broken plexi sun roof that was installed with windshield urethane, I'm assuming Silka is similar, I can't tell you how difficult it was to remove that plexi from the frame, hammer and sharp chizzle, many types of razor blades ect. The sharp broken pieces of plexi did not want to come off the frame. All I can imagine is if the canopy did break, there would be many sharp knife like pieces of the canopy remaining along the edges to cut the heck out of you.
