I'm not sure there is much art to the fitting.

Look at the description of Don Hammer earlier in this post:
"Day two-
The canopy comes oversize. Placed it on the still in place frame and
adjusted its position while overlapped and taped in place with clear
tape. Ran the cutoff wheel around and used the frame edge as a guide
removing all excess... Removed canopy and put a bead of
resin on the frame."

There is no fine fitting here. I'm removing my old canopy in prep for a replacement and find that the edge is uneven by millimeters, which fillers compensate for. Good adhesives have several thousand psi strength in tension and shear, so the adhesive takes the canopy load, not canopy to frame-lip contact.
