Quite right - it is known as Chloroform welding. Believe it or not I used to teach the technique to children (!) as part of their D&T course when I was a teacher in secondary school - carefully of course, and in a fume cupboard in a science lab. It works very well and is invisibly neat, but the surfaces have to mate perfectly - it won't 'fill' at all.
I am fairly sure it won't work with Polycarbonate.
