Sure, its a good acryllic vanish not unlike those used as a coating for artwork. These lacquers has been an integral part of art for centuries--- granted not acryllic but colophonium or some solution of natural resins of mastic, dammar, amber, copal, sandarac or even myrrh--- and were early-on adopted into photography.

Better than purchase aerosol cans I'd advice one to get the stuff in a bulk (1 litre tins). Should one need to spray, one can use airbrush..
