Single, two or three stage paint correction: which does your car need?
What each level of machine polishing does, how much of the swirls and scratches it removes, how long it takes and what it costs in Sheffield.

If your paint looks dull, or covered in fine circles when the sun hits it, machine polishing will fix most of it. How many stages you need depends on how deep the damage goes and how close to perfect you want the finish. Here's the short version.
| Package | Best for | Defect removal | Time | From |
|---|---|---|---|---|
| Single stage enhancement | Dull paint, light swirls | Up to 50% | 10 to 14 hours | £300 |
| Two stage correction | Clear swirls and light scratches | 65–75% | Around 20 hours | £600 |
| Three stage correction | Heavily marked paint | 80–90% | Around 30 hours | £900 |
What a stage actually is
A stage is one complete pass over the car with a particular combination of machine, pad and polish. Aggressive combinations cut away more clear coat and remove deeper defects, but they leave fine marks of their own, so every cutting stage needs a finer stage after it to refine the finish. More stages means deeper correction and more hours.
Single stage enhancement: bringing the gloss back
A single stage enhancement is one polishing step that balances cut and finish. The aim is gloss. It removes up to around half of the light swirls and haze, and for most cars it's the step that makes the biggest visual difference for the money.
It suits daily drivers, cars you're about to sell, and anything that looks tired rather than damaged. It starts at £300 for a small car and takes 10 to 14 hours.
Two stage correction: taking out the swirls
Two stage starts with a cutting step on a microfibre cutting pad to remove deeper swirls and light scratches, then a medium compound step to refine what the cut leaves behind. We aim for 65–75% defect removal.
This is the one for paint where you can clearly see spider-web swirls in sunlight, which describes most dark cars that have been washed with brushes or a sponge for a few years. It starts at £600 and takes around 20 hours.
Three stage correction: for heavily marked paint
Three stage uses a rotary polisher for the cutting step, which removes the deepest marks the clear coat can safely give up. Rotary machines leave trails of their own (often called holograms), so a mid step removes those, and a final refining step brings out the clarity and gloss. We aim for 80–90% defect removal.
It suits heavily defected paint: years of automatic car washes, a car bought in poor condition, or a car you want as close to perfect as the paint allows. It starts at £900 and takes around 30 hours.
Why nobody can promise 100%
Clear coat is thin, usually thinner than a sheet of paper. Some scratches go deeper than it can safely give, and removing them completely would leave the paint without enough protection. A good detailer works to a realistic target and tells you which marks won't come out before starting. That's why our packages are described as percentages, not promises.
How to tell which one you need
Take the car into direct sunlight, or shine a torch at the paint after dark, and look closely at the reflection of the light.
- Dull and slightly hazy, with only a few fine swirls: single stage enhancement.
- A web of circular swirls around the reflection: two stage correction.
- Swirls, plus scratches you can see from a few feet away: three stage correction.
Still not sure? Email a photo taken in direct sunlight to info@drccarcare.com and we'll tell you honestly which package is worth paying for.
Protect it once it's done
Polishing removes a little clear coat each time, so it isn't something you want to repeat every year. Once the paint is corrected, a ceramic coating locks the finish in. Our ceramic coating package includes a single stage enhancement and Reign's 7-year coating from £500, and you can upgrade the polish to two or three stage first.
