When getting my back window tinted I specifically asked for it to be done in 1 piece yet the shop tinted it in 2 pieces with the seam along the defrost line. Upon inspection it appeared a section of the defrost line had been cut and was missing, the owner stated it wasn't it was just where there was no tint on the seam. He re-tinted in one piece and now its clear the section is missing in addition to a couple other places. Does anyone know if the defrost line can be reapplied or if a new window would have to be installed. I would not want to replace the window if that's the case. Thanks for any insight.
