Yes, it is possible. The tint is integrated into the glass itself rather than being applied on top. Removing a thin layer through a cutting process does not affect the tint. For instance, many modern cars come with factory-tinted glass, and scratches in these panels can typically be removed without issue. However, for those who have aftermarket tint films applied to their car glass, scratches in the film usually cannot be repaired and the film will need to be replaced.
