"NOTE: The best fit can be obtained by ensuring that only the bare surface of the canopy directly contacts the aircraft structure.
May I also suggest that you consider sealing the forward edge of the rear window where it contacts the Roll Over Structure. On my first flight through rain, there was water ingress in that area. I outlined my approach here
. I used siliconized latex caulk (because it's paintable - be careful what you use). It's not visible.
Please also consider painting the perimeter of your rear window where it contacts the F-01474 Aft Fuse Top Skin. If you don't, the sealant will be visible and its aesthetic may not be desirable. I outlined my approach here
Prior to final install...
You might also consider putting a tiny bit of sealant along the skin joints on the exterior too, to prevent water ingress. I did this for the Rear Window and Canopy. Below is shown the Rear Window. I outlined my approach here
Very clean looking edges after sealant application...
Finally, I had to use a pair of additional washers to keep the surface profile of my Rear Window correct (i.e.
, prevent it from forming a depression) where it meets the F-01432A Roll Bar Brace. Without those extra washers, the Rear Window curvature in that area would 1) droop downwards and 2) not match that of the Canopy. Also, as you can see below, it's clear that this area is a great place for water ingress if not sealed as I outlined above.
