A couple of follow-up notes on using any glue to attach the canopy.

The first is make that the structure being glued to is in its "installed" shape. I replaced the 6 screws with RC56 glue to attach the canopy to the hatch but Idid it on the bench - NOT with the hatch installed on the fuse. As a result the hatch's shape changed enough to mis-align the side hatch mounting screws. When trying to apply a bit of persuasion at the field my finger went through the canopy (I believe that is was significantly weakened by painting the underside with auto paint making it very brittle). As a result I fabricated a new hatch and ordered a new canopy from Hanger 9.

The second installation was done with the hatch afixed to the fuse with the side mount screws. The canopy was dry fitted and then marked for installation alignment. Thin 1/16" strips of Ultracote were removed and the RC56 applied. The canopy was installed using the alignment marks. After the glue dried the entire perimeter was covered with matching Ultracote strips using low heat to avoid warping the canopy. The leading edge of the canopy looks a bit like Donald Duck's bill but it's not bad. Everything will be nicely fuel proof.
