Hi. You may have read I'm giving my friend a gently used Husqvarna/Viking Lily sewing machine for a surprise gift. The only wear and tear on the machine is a line of scratches made from the placing and removal of the case as it slides over. I'd love to buff these out if at all possible, but I'm not sure it is. Does anyone know if it's possible to buff out scratches from plastic, and if so, how? Thanks! :?:
