No one has mentioned it so I will.

RC-56 Canopy Glue.

1. Cut your canopy to fit.
2. Put a bead of the glue on the mating surface of the canopy.
3. Put in position and TAPE in place.
4. Clean any glue that seaped out with water and paper towels.
5. Come back the next day and remove the tape.

RC-56 will glue just about anything to anything else. It dries clear and can be cleaned with water and paper towels WHILE IT IS STILL WET, Fuel will not affect it (at least in my experience). To remove the canopy use a NEW #11 blade and CAREFULLY slide the blade between the canopy and the covering and cut the canopy off.
