The polishing set deluxe is suited to remove scratches and dull spots from clear plastic sheets. This set is recommended for dealing with deep scratches and large dull areas. Start by applying the Heavy Cut polish to the damaged area, use the Fine Cut polish to bring the sheet back to its original crystal-clear state. The polishing disc easily centres itself, reducing excessive vibrations. 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.
