Odd question, I am trying to stick an older sticker to the inside of my window. It has lost its stickiness and wont stay up anymore I have tried super glue but i think it is too hard and cracks off with temperature change. My next though was rubber cement but i dk if that dries really clear. Or does anyone know what tint shops use to keep the edge of the tint down if they bring it all the way to the top edge?
