Before you start
Correction magnifies whatever is on the paint. Any grit left on the surface goes under the pad and gets ground into the clear coat, which produces new defects while you are trying to remove old ones. So the preparation is not optional and it is most of the day.
Wash with the two-bucket method, decontaminate chemically with an iron remover, decontaminate mechanically with clay, then dry completely. Only then does a machine come out.
The sequence
- 1Inspect under a light. A single point source held at a low angle, moving your head. Diffuse light hides everything you are about to spend a day removing.
- 2Tape everything the pad can reach. Plastic trim, badges, panel gaps, rubber seals. Eight dollars of tape prevents the two most common beginner mistakes.
- 3Do a test section. One 2ft by 2ft area, least aggressive combination first. Wipe with panel wipe and inspect. Step up only if it was not enough.
- 4Prime the pad. Three or four pea-sized drops spread across the face. Too much compound clogs the pad and stops it cutting.
- 5Work slowly, in overlapping passes. Roughly an inch per second, four to six passes per section, keeping the pad flat. Speed does not correct; contact time does.
- 6Keep the machine flat and let it work. Pressing stalls a random orbital, which means it stops correcting entirely. Let the weight of the machine do it.
- 7Wipe and inspect after every section. A clean low-GSM towel and the light again. This is what stops you doing a whole car wrong.
- 8Panel wipe when finished. Removes polishing oils so protection bonds and so nothing is hidden.
- 9Protect the same day. Freshly corrected clear coat has nothing on it. Coating, sealant or wax.
The three mistakes
Pressing
The instinct is that harder equals more correction. On a random orbital it means the pad stops rotating, so the machine is now vibrating rather than cutting. If a defect is not coming out, change the pad or the compound, not the pressure.
Working in the sun
Compound flashes on a hot panel before it has finished breaking down, which leaves it dry on the paint and difficult to remove. Work in shade, on cool panels, and if the car has been sitting in the sun, wait.
Not inspecting
Correcting a whole car and then discovering the combination was wrong is a day lost. The inspection after each section takes fifteen seconds and it is what turns a correction into a controlled process rather than a hopeful one.
How long it takes
A one-step correction on a mid-size car is a full day the first time, and perhaps six hours once you have done it a few times. A two-step is a weekend. Preparation — wash, decontamination, taping — is two to three hours of that before the machine is switched on.
If that sounds like a lot, it is worth knowing that this is exactly what a professional correction is billed for, and it is why a coating quote is mostly labor. The difference between the two is a machine you keep.
Every pick, with the working
Each entry lists the specifications the maker publishes, the axis scores those specifications produce, and what you give up. Rows that read “Not published” are not omissions on our side: they are figures the maker will not commit to in writing, and they cost the product points on the transparency axis.
Our pickThe upgrade most people should actually make
Griot's Garage G9 Random Orbital Polisher
Griot's Garage
$179.99 for a 9mm orbit driven by a 1,000-watt motor, shipped with a 6 inch vented backing plate and convertible to 5 inch. A 9mm throw finishes cleanly and asks less of your technique than a long throw; the 1,000 watts is what stops it stalling when you lean on a curve.
- Orbit throw
- 9mm
- Motor
- 1,000 watt
- Backing plate
- 6 inch vented, converts to 5 inch
- Cord
- Detachable
- Counterbalance
- Patent pending fan-cooled
- Speed range
- Not published
- Weight
- Not published
- Warranty
- Not published
What it does well
- 1,000-watt motor published, which is more power than most 9mm machines carry
- Ships with a 6 inch plate and converts to 5 inch, so pad choice is not locked in
- Detachable cord, published, which is the difference between storing it and wrestling it
- Fan-cooled counterbalance, which Griot's states extends tool and pad life
Who it is not for
- No speed range published on the product page, which is the second number you want
- No weight published
- No warranty term published on the page despite Griot's reputation for standing behind tools
How this score was calculated
- Protection claimdropped
- Nothing in this category is bought on how long it lasts, so the axis is dropped and the other weights are re-normalized.
- Published orbit throw2.5/10, weight 22%
- 9 mm, scored on a band running from 5 to 21. Published by Griot's Garage.
- Cost per ouncedropped
- This is not a consumable, so cost per ounce says nothing useful and the axis is dropped.
- Price against the ceiling5.5/10, weight 14%
- A listed $179.99 against the $400 one upgrade in this category realistically tops out at. A list price captured on the compile date, not a live price and not what you will pay.
- Written commitmentdropped
- Griot's Garage publishes no warranty term on this product's own page, so the axis is dropped. On a tool that is worth noticing, and it costs the product points on transparency instead.
- Spec transparency6.3/10, weight 18%
- 5 of the 8 specifications we went looking for are published by Griot's Garage. Every blank row below is something the maker will not put in writing, and it costs the product points here.

2The one-pad answer for light to moderate defects
Chemical Guys Orange Hex-Logic Quantum Cutting Pad
Chemical Guys
$12.49 for 5 inch or $14.49 for 6 inch, described as a medium-cutting pad for swirls, light scratches, oxidation and water spots. If you are buying one pad to go with a one-step polish, this is the cut level that matches.
- Sizes
- 5 inch / 6 inch
- Cut level
- Medium cutting
- Stated defects
- Swirls, scratches, oxidation, water spots
- Thickness
- Not published
- Density
- Not published
- Stated pad life
- Not published
What it does well
- Defect list published explicitly rather than left as 'medium cut'
- 5 and 6 inch sizes at a $2 difference
- The Hex-Logic face is stocked everywhere, so replacements are never a special order
Who it is not for
- No density, pore count or thickness figure published
- No stated pad life
- Buying pads by brand color is a habit worth breaking; colors are not standard across makers
How this score was calculated
- Protection claimdropped
- Nothing in this category is bought on how long it lasts, so the axis is dropped and the other weights are re-normalized.
- Capabilitydropped
- No single published number decides capability in this category, so the axis is dropped rather than invented.
- Cost per ouncedropped
- This is not a consumable, so cost per ounce says nothing useful and the axis is dropped.
- Price against the ceiling7.5/10, weight 14%
- A listed $12.49 against the $50 one upgrade in this category realistically tops out at. A list price captured on the compile date, not a live price and not what you will pay.

3One-step correction on most paint
RUPES DA Fine Compound
RUPES
$14.99 for 8.5 oz, developed in-house by RUPES to combine cut with a finish that does not need a second step. On medium-hard clear coat with an intermediate pad this is the one-step answer, and one step is most people's whole job.

- Tool compatibility
- Large-stroke random orbital and gear-driven DA

- Designed for dual action machines, both large-stroke and gear-driven
- $1.76 an ounce at 8.5 oz
Who it is not for
- No cut rating published
- No coverage figure published

How this score was calculated
- Protection claimdropped
- Nothing in this category is bought on how long it lasts, so the axis is dropped and the other weights are re-normalized.

4Coating removal and general work, at the lowest GSM here
Eagle Edgeless 350
The Rag Company
$18.40 for a five-pack of 16 by 16 inch towels at a published 350gsm. A lighter towel is the right towel for leveling a coating: heavy plush grabs residue and drags it, and 350 is where control starts.

What it does well
- 350gsm published, and the lower weight is a feature rather than a compromise for this job
- Five towels for $18.40, the best per-towel price in this group
- Edgeless and tag-free, so there is no seam to drag across fresh coating
Who it is not for
- Too light for drying a whole car
