It will work okay, especially for mild curves. Sharper bends would need a torch or heat strip to do well. The key is not to get it too hot. It will bubble up on you if you do. The moisture inside starts to boil I think and that creates the bubbles.
I may be best to lay it on something with a similar curve like a barrel or can or pipe or something. Then getting the whole part up to the right temp, it will lay down around it just with gravity.
Once bent, you can quench it with a wet rag and air. Once cooled, it should retain that shape.
