One stage, two stage, three: matching the cut to the damage
Polishing jobs are specified in stages, and the stage count is what drives both the hours and the price. A single-stage polish uses one all-in-one compound on a medium pad: it removes light swirls and adds noticeable gloss in roughly 2–4 hours on a sedan. It is the right call for a well-kept car that has picked up typical UAE wash-and-dust marring, and in this market it generally lands around AED 200–400 for a sedan.
The professional way to set the stage count is a test spot: the technician tapes off a half-metre square, works it through a proposed combination, and shows you the result under the inspection light next to untouched paint. If it satisfies you, that combination becomes the spec for the whole car. A vendor willing to do this before you commit is telling you something reassuring about how they work.
