Back on the project today and back to the canopy fibreglassing. We started by removing some more of the 'lip' on the forward edge of the plexi - this should help the flow of the glass ply lay up.
Then it was a good scuff with 280 grit paper for the plexi and AL skin.
Clean down was just air and damp cloth.
Then we made some paper templates on baking sheet for the 'first' and 'last' versions.
 
Then lots of masking, again we used green masking plus a couple of layers of electrical tape.
Then a really stiff mix of silca (5 shots to 2 pumps of resin) I filled the lower gap between the plexi and skin.
Then the forward surface was roughly smoothed. I also brushed some resin / black paste on the forward plexi - next time I'm not sure if I would do this, I think the colour may have seeped slightly - but I won't curse and swear until I know......
I pasted some 6oz cloth up with resin and Dad cut it into strips. It was then slid off the backing and laid onto the work area.
The first few layers were thin 1/2" / 1" strips and progressively got bigger and wider.
About 6 layers in total were put on and then a final 2oz wide strip.
The finishing was done with peel-ply - first time I've really used this, but in theory it should help smooth the final surface and reduce / remove excess resin.
 
This is the finished result at the front - not perfect, but a good first stab. More filler and lots of sanding will be needed to get a finished transition from skin to plexi.
