The key is to roughen the plastic to the point that the epoxy has something to hold to, just like Mark L. said!
-------------- I talked to a friend that make aircraft Canopies, He told me at Polyester resin is the BEST to stick to the canopy. You can run a layer of say 2 to 3 inches tape around the inner and out areas where you wish to glue, when dry use epoxy to glue to the polyester strip. PLEASE try epoxy and polyester on a test cut off from the canopy, ( leaving a length of tape as a handle) you will see you can PULL the epoxy off the canopy, but not the polyester.
