1. Some papers are better for emulsion transfer and some are not.
2. It's better to wet the pola negative in an alkaline solution, it helps the emulsion to detach and stick on the paper.
3. I don't think a glue would be a good idea.
4. In the past, I had some success with Fuji instant, but Polaroid 4x5 was better. If you want something easy and quick, try to spray some window cleaner on the negative just before sticking it on the paper. Apply gentle pressure with a roller for 1 minute, then peel. I did that in a shop where I used to work (printing and doind passport Polas) with every Passport picture's negative I used. It worked most of the times. The only material I had in hand was Ajax window cleaner and a fat permanent marker for rolling... If you don't wait for the pola to print on its own paper, it's even better...
