crazy selling black front projection film

rear projection film transparent  installation method:

You stick the rear projection film like a car stick one film on glass. the first, you need to clear the glass with water,  spray Sprite drink on glass again (we recommend use Sprite  drink to stick the film and make better projection show.)
and the rear projection film has two layers.then you can remove the protected layer and stick film on glass and adjust the film position, then you can use rubber  squeegee to squeegee the water from center to the edges and when you make sure there is no water between the glass and film. done.
