The film-free laser paper comes with a small bottle of glue. I also wanted to see how it would work if I used Varathane water-based Polyurethane instead of glue.
Both methods worked well, but I think the method of using the glue that comes in the package won out. The alcohol did an awesome job of cleaning up the left over glue. I’m not sure what kind of glue it is, but it is not gooey at all. It was actually rather thin and painted on easily.
