I contact GP and they sent me another canopy for free.
it'll take about a week ...so call them now

that warpage will be noticeable even after triming.

that's why i just paint the inside black sometimes so it dosn't look too intence.

if you use CA you'll get a fog and sometimes epoxy runs everywhere.

I glue two berch wood rails to the side of the cockpit and just screw the canopy in place.
