HOW IT WORKS
Three steps to a clearer finish
Sandpaper, polishing pad and compound are all you need. S9 handles the heavy and medium steps with one bottle, and a deep mirror finish is optional.
Prep and sand
Wash and dry the panel, then finish sanding. A clean, dust-free surface lets the compound cut evenly and keeps the pad working the way it should.
Polish with the right pad
Apply S8 or S9 to a polishing pad and work in overlapping passes at a controlled speed. Match the pad to the job: cutting pads for defects, softer pads for gloss.
Wipe off and inspect
Remove residue with a clean microfiber cloth and inspect the panel in good light. Repeat on deeper defects, and add a softer-pad pass when you want a deep mirror finish.
BEFORE AND AFTER
From sanding marks to gloss
The process is simple to follow, and the result is easy to see on the panel.
- Sanding marks lifted from prepared panels
- Scratches and swirls removed from painted surfaces
- Gloss and depth restored, with a deep mirror finish when you want it
