There could be a technology that uses nanotechnology, that is activated by a catalyst such as a specific type of light, such as UV light, to repair surfaces such as glass, by filling in scratches on the glass – whether it be gorilla glass or eye glasses, or a window on a car or house.
The nanotechnology could be made specifically to repair specific types of surfaces.
The technology could also be adapted to automatically sand a surface down, by applying the liquid with the nanoparticles that resonate at a certain frequency of light, and then can be removed with a solvent. It would take the hard work out of sanding a surface.
