There are a couple of plusses you get from canopy glue. It dries clear, so clear it's basically invisible. Any excess on the inside simply won't be noticed. When you're gluing the canopy on, any excess that shows on the outside is easily wiped away with a damp paper towel. The installation looks great and is no risk to do.

I've only chosen to remove one canopy in the past 5 years and used an extra thin blade. The glue holds solidly but parted with just a bit of effort. The canopy was in good shape and so was the fuselage. It dawned on me after I had the canopy off that I could have more easily cut the cockpit floor out to put the reflector sight in. Live and learn.

My current project has some glue-on fixtures on the bottom of the wing. The heavy one got epoxied on while the others got canopy glue. The epoxied one didn't fit very well and there were some gaps where the epoxy wasn't thick enough (I use as little epoxy for this kind of job as possible.) so after the epoxy had cured I ran a bead of canopy glue along the gaps to seal. Worked great.
