A cut and polish removes a fine layer of tired clear coat to clear away marring and haze, then refines the paint back to a deep, wet-looking gloss.
'Cut and polish' is the everyday name for paint correction — cutting back a little clear coat to remove defects, then polishing to bring the shine up. A single-stage cut is a cost-effective way to freshen tired paint; a multi-stage cut goes further for heavily marked cars.
It's ideal before selling a car, or as the prep step before a ceramic coating. We'll recommend the level that gets you the result you want without over-working the paint.
