How long does a full polish take?
the desk replies — A single-stage polish on a sedan takes roughly 3–4 hours including the wash and decontamination; a two-stage correction runs 5–7 hours; a three-stage job on an SUV can fill a working day. Quotes promising a full machine polish in under two hours are compressing the preparation stages, and the finish will show it within a few washes.
