The basic polishing set is suited to remove scratches and dull spots from clear plastic sheets. The scratches will vanish easily with Zvizzer Heavy Cut polish. The polishing cloth deluxe deals with deeper damages to the sheet. Use the soft micro-fibre cloth for the finishing touch. Because Zvizzer is a water-based polish, is will be easy to judge the polishing progress. Unlike oil-based polishes, a water-based polish does not fill up scratches, making them easy to see while doing the job.
