I've had good luck using silicone II, the bath and window type caulking. I lightly trace the area the canopy contacts the fuse, poke a bunch of small holes  through the covering with T-pins and lay a bead of caulk down. place the canopy, clean up any that squeezed out, then tape down the canopy over night. There is just enough give in the caulk to keep vibrations from loosening the canopy, yet it's a very tight bond and the silicone is readily available.
