In many cases it is best to have a second set of hands, the rear projection film adhesive is very sticky. If the film gets stuck to the liner when being removed or stuck to glass without liquid it will not come off easy or in usable condition.
Depending on the size of the piece of rear projection film and quantity you have to install, you will want to prepare enough liquid without having to refill. You can order additional fluid refills based on the size of your project.
