Paint correction is the permanent removal of defects from a clear coat by abrading the surface until it is level. It is permanent in both directions: the defects do not come back, and the clear coat you removed does not either.
02
The finite resource nobody mentions
A factory clear coat is roughly 40 to 50 microns thick on most modern cars, and a meaningful correction removes somewhere between 2 and 5 microns. That arithmetic is why correction is not a routine job: a car has perhaps five or six full corrections in it across its whole life, and after that there is not enough clear coat left to work safely.
This is also why the single most valuable thing you can do for your paint is not polish it — it is wash it properly so it does not need polishing. The two bucket method prevents the defects this page removes.

For a daily driver the honest answer is almost always a one-step. It removes the defects people actually notice, it finishes well enough on most paint, and it spends the least clear coat for the visible result. Multi-step correction belongs on show cars and restoration work.

Best for: The default answer for a first serious machine
A 9mm throw and a 1000W motor put the G9 exactly where most home detailers should be: fast enough to finish a car in an afternoon, short enough in the throw to stay predictable near badges and body lines. It is the machine we would buy if we were buying one machine.
Who should skip it. If you already own a competent 8mm machine, this is not the upgrade you think it is — the extra millimeter of throw will not fix inconsistent results. Put the money into better pads and a second liquid instead. It is also heavier than the G8, and you notice that on vertical panels after an hour.

What works
9mm throw is the best general-purpose compromise on the market
1000W does not bog down under pressure on a cutting pad
Griot's lifetime warranty is the strongest in the category
Takes the same 5 in plate and 5.5 in pads as everything else
What does not
Heavier than the G8, which shows on doors and quarters
Menzerna's heavy cut is what people reach for when a daily-driver compound has made no visible difference, which happens on hard European clear coat more often than anywhere else. It cuts hard and, unusually for its grade, finishes well enough that one follow-up polish is normally enough.
Who should skip it. Soft paint and light swirls, where it is simply more abrasive than the job needs. The listing here is a 128 oz jug, which is far more than a home detailer will use in years.

Perfect Finish is the liquid you reach for when the correction is done and you can still see haze under direct sun on black paint. It cuts enough to remove light defects on soft paint and finishes to a genuinely clear gloss that a compound cannot match.
Who should skip it. Defect removal on anything but soft paint. If there are swirls you can see at arm's length, this is the second liquid, not the first.

Lake Country makes the foam a great many other brands rebadge, and the HDO line is built specifically for the pressure a long-throw machine puts through a pad. A three-pack of the same pad is more useful than four different ones, because a saturated pad stops cutting and you need a spare mid-panel.
Who should skip it. Short-throw machines under heavy pressure — HDO foam is designed around orbital machines and is firmer than a general-purpose finishing pad. If you only ever finish, buy a softer foam.

01Wash, decontaminate and dry. Non-negotiable — see how to polish a car for the full prep.
02Tape edges, badges, trim and body lines.
03Test a 2 ft section with a polishing pad and a hybrid compound. Step up to a cutting pad only if that is not enough.
04Work the whole car in 2 ft sections, horizontals first.
05Swap pads every two to three panels. A saturated pad stops cutting.
06Inspect each panel under a light before moving on.
07Wipe down with a panel prep spray if a coating is going on next, to remove polishing oils.
08Protect the same day.
06
The two-step process
Everything above, with one difference: the first pass uses a heavy cut compound on a cutting pad, and a second complete pass follows with a finishing polish on a soft pad. That second pass is what removes the marring the compound left.
The reason to do this is specific: hard clear coat that a hybrid cannot cut, or dark paint where compound haze is visible. On a silver daily driver it is hours of extra work for a result nobody can see. Compound vs polish has the test that tells you which camp you are in.
07
Judging the result honestly
Direct sunlight, low angle, sun behind the panel. This is the only lighting that shows the truth.
A handheld inspection light at a shallow angle in a dark garage is the next best thing, and more repeatable.
Look at the same spot before and after. Memory is unreliable; take a photo of the test section first.
Accept some defects. A perfect finish on a daily driver is not a realistic goal, and chasing the last 5% is where people polish through.
Then change how you wash it. Every swirl this process removed was put there by a wash, and without changing the routine you will be back here in two years with less clear coat to spend.

Questions people actually ask
What is paint correction?
The permanent removal of defects from a clear coat by abrading the surface until it is level with the bottom of the defect. Unlike a glaze, which fills and hides, correction removes — which is why the result lasts and why it uses up clear coat.
How many times can you polish a car?
Five or six full corrections across a car's life, roughly. A factory clear coat is about 40 to 50 microns and a meaningful correction removes 2 to 5. Spot work uses far less, which is why addressing individual defects beats correcting the whole car repeatedly.
Is one step or two step paint correction better?
Better for what. A two-step removes more and finishes better on dark or hard paint; a one-step removes the defects most people notice in roughly half the time and spends less clear coat. For a daily driver, a one-step is usually the right call.
Do you need paint correction before a ceramic coating?
You need decontamination. Correction is situational: a coating locks in whatever the paint looks like for years, so any swirl you leave is sealed in. On new paint a chemical decon and panel wipe is often enough — see do you need to polish before coating.
