Anti-graffiti film is most useful where the glass is expensive to replace, awkward to access, or highly visible to customers and the public.
For many shopfronts, the biggest value is not just the material cost. It is the ability to restore the surface faster and avoid the disruption of replacing the full pane.
This type of film is also useful on mirrors, lifts, display glazing, transport shelters and other smooth surfaces that are likely to be scratched, tagged or etched.
If the main concern is forced entry rather than surface damage, anti-graffiti film may not be the right primary solution. That is where a safety or security film discussion becomes more relevant.
