The canopy skirt is looking better all the time. I put some more fibreglas at the back to properly tie the left and right halves together, and it seems fairly strong now. I need to get a bit better fit right at the centre, where it fits around the raised canopy track.
When I put the fibreglas layer on to tie the two halves together at the back, I put a layer of wax paper over the canopy track, and tried to form the fibreglas closely over it. It was definitely a mistake to use the wax paper, as some of the wax paper stuck to the fibreglas, and it was a pain in the butt to get all the wax off. I would use electrical tape next time.
The fibreglas didn't fit real tight over the canopy track in the back, so I tried a bit of an experiment. I put some electrical tape over the canpy track and the surrounding fuselage skin, then stuck some West Systems epoxy and microfibre under the back end of the canopy skirt and then closed the canopy tightly. In theory, I should get a nice tight fit over the canopy track.
This canopy skirt was removed when this picture was taken. You are looking at the aft end of the plexiglas canopy, with a bit of electrical tape on it which kept the fibreglas resin from sticking when I bonded the two halves of the canopy skirt together.
Here you see the back end of the canopy skirt, after I tightened it down with the epoxy and microfibres in the gap.
