Iv'e tried some of the other methods, but really don't care much for the torch. What works best for me is to scuff/ dull the surface area to be glued with a "scoth bright" pad. Some people call it artificial steel wool. And then use E6000 industrial adhesive, I get it at Hobby Lobby craft stores (not hobby lobby the model store). We use it for lots of stuff it dires clear and is flexible, and very strong. I think Wal-Mart carries something like it call "Welder" ??? It come in tube like toothpast. The only disadvantage must dry overnight for strength. But is very convenient and strong.....
