Mirror scratch repair This is a clean example of a glass mirror scratch repair that saved a large 290x120cm mirror from being replaced in a shower room, the mirror also had a heating element and is glued to the wall which makes it very hard and costly to replace. 1 The scratch was very obvious and right in the eye line from every angle in the room 2 after the polishing repair there is no mark of the scratch and the mirror is saved from replacement. see more repairs
