I just rebuilt my canopy. It was not as bad as I expected. I used plastic pipe tape and it worked great.
This is how I taped it before epoxy. The plastic tape bends around the curves very much like pin stripe tape. It is 20 mil thick so great protection. A good coat of wax and it popped off great.
Here is the rough finished piece after pulling it off the canopy. I will sand, prime, and then glue it on.
There are a few more pictures of my canopy rebuild here. Hope the links still work!
