Invisible Windshield Protection Film Royal Shield Invisible Windscreen Protection Film is the first and only optically-clear protection film for vehicle windscreens. The film absorbs the impact of normal road hazards – significantly reducing the occurrence of pitting, stone chips, star cracks and bull’s eyes – leaving the glass in pristine condition. In the event of an accident the security film will help maintain the integrity of the windscreen protecting the occupants. The film is warranted not to peel, bubble, crack or yellow. Royal Shield film is thermally fitted to every curve of the windscreen, forming a bond with the glass, and ensuring optical clarity. Security film compliments the window tinting package, giving you complete protection from the sun whilst protecting your windscreen against accidental damage.
