Paint correction

Your paint is not dull. It is scratched, and the scratches came from washing it.

Adam's says so on its own product pages. The harder question is what takes them back out, and which number on the machine decides.

Updated August 18, 2026 · 14 minute read

You saw it in a parking lot, or at a gas station under the canopy. Fine circular scratches across the hood, arranged in a web, sliding as you move your head. An hour earlier, in flat shade, the same panel looked perfect.

Most owners file that away as age. The paint is nine years old, the sun has been on it, that is just what happens. It is a comfortable explanation and it is almost entirely wrong.

Adam's answers this on the product page for one of its own machines, which is an unusual place to find a straight answer. The question is printed as a heading, in the middle of a page selling a polisher: what causes swirls?

01  The cause

Nothing on the road put those marks there.

You’re probably wondering how your paint got into the condition that it is, to begin with… that answer is much more complex depending on the scenario but it's generally a mix of: Improper washing. Each time you touch your vehicle, whether to simply wipe it down, or to dry it after a foam bath with Car Shampoo, you run the risk of damaging your finish and swirling your paint. Adam's Polishes, SK Pro 12mm Swirl Killer Polisher

The same passage names the specific failures: a dirty drying towel, no drying aid to lubricate the surface, no Grit Guard or Dirt Lock to clean the wash pad out between panels. All of it, in their words, introduces micro-marring, swirl marks, or deeper scratches into your finish.

Read that as a mechanism rather than a warning and it becomes obvious. A wash mitt is a sponge for grit. It picks up sand from the lower rocker, and unless something strips that grit out of the fibers, the next pass drags it across the door. A dry towel on a dry panel does the same thing with whatever is still on the surface. Nothing here requires carelessness. It requires only a normal Saturday, repeated for a few years.

Which means the damage has a very specific signature. It is shallow, it is even, it covers the horizontal panels worst, and it is concentrated exactly where hands go. Hood, roof, trunk lid, the top of the doors. Look at a rocker panel that nobody ever wipes and it is often cleaner than the hood.

02  The optics

A scratch you cannot feel still changes the color of the car.

This is the part that makes swirls maddening. Run a hand over the hood and it is glass. Look at it in the shade and it is fine. Then one strip light passes overhead and the entire panel turns grey.

The reason is not chemistry, it is geometry. A flat clear coat sends a beam back the way a mirror does, in one direction. Score that surface with thousands of shallow arcs and each arc becomes its own little curved mirror, throwing light out at every angle at once. Your eye reads the returned haze as dullness. The pigment underneath has not changed at all.

That is also why the fix has a tool of its own. Adam's sells a Swirl Finder Flashlight for 14.99 dollars. It polishes nothing. Its only function is to give you a hard point source in a garage so you can see what you are working on, and see when it is gone.

Company history and the guarantee are stated on their About page. The review total is the count returned by the public review feed on adamspolishes.com, read on August 18, 2026.

03  The fear

Rotary buffers earned the fear. This is a different tool.

Everyone who has hesitated over a machine polisher is picturing the same thing: a body shop buffer, a burnt patch of primer, a very expensive Saturday. That fear is well earned, and it belongs to a category of machine that Adam's does not sell for this job.

They draw the distinction themselves, twice, on two different product pages:

Dual action polishers differ from rotary buffers in that rotary buffers have fixed rotation and spin only in a circular motion without oscillating the pad. Rotary buffers are rated in Revolutions Per Minute (RPM) as opposed to the Oscillations Per Minute (OPM) of a Long Throw Dual Action Polisher. Adam's Polishes, Swirl Killer 15mm LT Polisher

A rotary spins one point of the pad over the same arc of paint, continuously, and it does not stop generating heat until you move. That is what burns clear coat and what leaves what Adam's calls holograms or buffer trails. A dual action machine adds a second, free axis: the plate orbits while it also turns, so no point of the pad stays over the same point of paint. Adam's describes the result as mimicking how a hand moves in an irregular circular pattern, several thousand times per minute.

Forgiving is not the same as impossible to get wrong, and it would be dishonest to pretend otherwise. Somebody wrote this on the product page for the entry machine, and Adam's published it:

Being a novice at this machine polishing, this polisher feels great in my hands. It is very easy to move around my truck with this. Flattening paint spots is still a work in progress. I managed to burn through the clear coat in two spots. Still learning but I really like this machine! Anonymous, review of the Swirl Killer 9mm LT Polisher Basic Kit, published August 28, 2024 on adamspolishes.com

Note what he was doing when it happened: flattening paint spots, which means sitting in one place and pushing. That is the one behaviour that turns a forgiving machine into a rotary. The controls that prevent it are on the spec sheet, and this is where reading the spec sheet starts to pay.

04  The number

Throw is the spec that decides what the machine can do.

Wattage is the number people compare, because it is the number they understand from other tools. On a dual action polisher it is close to irrelevant. The number that decides the character of the machine is the orbit throw, printed in millimetres: how wide a circle the backing plate travels while it is also spinning.

Adam's is unusually direct about the trade, because they sell every step of it:

Long Throw Polishers typically have a 15mm or 21mm orbit pattern. While a 21mm throw can correct imperfections a little more quickly than a 15mm throw, the larger orbit and larger pad size for these machines can make them a little more difficult to use on some vehicles with very complex curves. Adam's Polishes, Swirl Killer 15mm LT Polisher

Their own recommendation, written on the 15mm page, is not the biggest number they sell: they chose 15mm with 5.5 inch and 6.5 inch pads for it to be more versatile for most of our customers. That sentence is worth more than a comparison chart, because it is a company telling you not to buy the flagship.

05  The ladder

Nine machines, one table, their own published numbers.

Adam's does not put its polisher range side by side anywhere, so here it is. Every figure below is copied from the product page of the machine in question. On a phone the table slides sideways, and weight, power and price are the three columns worth sliding to.

All figures and prices as published on adamspolishes.com and read on August 18, 2026. Prices shown are the polisher only configuration where several are offered. "Not published" means the specification is not stated on that product page.

Two entries on that table deserve a warning label, and Adam's supplies both. The MINI 12mm page says plainly that it is not designed or intended to be used to paint correct an entire vehicle. The Micro is a 1.5 inch plate for emblems and trim. Neither is the machine that does your hood, whatever the price makes you hope.

06  The ceiling

More oscillations per minute is not better, and they say where the line is.

Speed reads like horsepower on a spec sheet, so it gets compared the same way. Adam's contradicts that on the SK Pro 15mm page, in a sentence that no marketing department writes by accident:

Having a speed over 5500 OPM is effective for paint correction, however, raises the risk of burning your paint as your displacing paint and friction faster than usual. Adam's Polishes, SK Pro 15mm Swirl Killer Polisher

Hold that line up against their own range and the table stops being a list of products and starts being a set of decisions.

The full size machines that top out at or under the line are the two 15mm long throws and the two 15mm machines built for whole cars. The ones that run past it are the small plate machines meant for spot work, where you are on a mirror cap for thirty seconds, not on a roof for an hour. That is a coherent design position and it is legible only if you put the numbers next to each other.

The practical version, from the MINI page: most swirl mark removal can be achieved at speed setting 3 or 4, with 5 and 6 reserved for heavier scratches. Almost nobody buying their first polisher believes that, and almost everybody ends up there.

07  The cord

The variable that never appears on a spec sheet.

Here is the part of this that took years to become obvious, and it is visible in Adam's own product copy if you read two pages next to each other.

On the SK Pro, the cord is engineered as a hazard to be contained. Their words: the machine offers a durable, scratch-resistant cord, meaning that if you happen to scuff your paint with the cord, you're safe from doing any heavy damage. Read that again. The premium feature is that when the cable hits the paint, it hits it gently.

Which makes sense once you picture the actual job. You are at the far rear quarter with a 25 foot cord running back to a wall socket, and the cable is lying across the roof and the hood, the two panels you have just spent an hour correcting. It moves every time you move. And an hour of polishing dust and compound spatter has been settling on it the whole time.

That quotation is not an outside opinion. It is the description Adam's wrote for the cordless 15mm, on the page where they sell it, and it names the exact failure the cord causes: unnecessary scratches from accidentally bumping a dirty power cord into a panel.

Which closes an odd little loop. The defect you bought the machine to remove is put there by dragging a contaminated object across the paint. So is this one.

08  The trade

What cutting the cord costs, in weight and in minutes.

Batteries are heavy and they run out. Both objections are real, and both are answerable from the published numbers rather than from opinion.

Start with weight, because the intuition is wrong. A full size cordless machine ought to be the heaviest thing on the table. On Adam's own figures it is the lightest full size machine they publish, battery fitted.

Then runtime, which is the objection that actually has teeth. Adam's publishes it precisely: 30 to 45 minutes under load per battery, two 5.0Ah batteries in the box, and 60 minutes to charge one. Put those three numbers in a line and the arithmetic resolves itself. The second battery finishes charging before the first one is empty, so the machine never actually stops. It is a swap, not a break.

The rest of the cordless 15mm spec is ordinary competence, which is the right kind of boring: brushless motor, 5 inch backing plate taking 5.5 and 6 inch pads, six speed levels on a dial plus a variable speed trigger, a trigger lock so your finger is not holding it for an hour, and an integrated dust screen to keep polishing dust out of the motor.

09  The protocol

Four steps, three pads, two speeds.

This is the whole method, and Adam's prints it at the bottom of a product page where nobody looks. It is reproduced here exactly as they give it.

1. Heavy defectsCompound with the Microfiber Cutting Pad, speed 4 to 5. Brush the pad with the Pad Conditioning Brush after each pass.
2. Mild defectsCompound with the Blue Compound Pad, speed 4 to 5.
3. Second stepPolish with the White Polish Pad, speed 4 to 5.
4. Protect, and this one is not optionalIn their words, be sure to always protect your paint upon polishing as you're removing the existing protection.

Steps 1 to 4 as published on the SK Pro 12mm product page, read August 18, 2026.

Step 4 is the one people skip, and skipping it is worse than doing nothing. Polishing abrades the surface, so it takes the wax or sealant off with the defect. A freshly corrected panel is a bare panel. Leave it bare and it starts collecting the next generation of swirls immediately.

10  The owners

What people report once the machine is in their hands.

All of the following are published on adamspolishes.com, on the product page of the machine named. They are quoted exactly.

Notice how many of them mention watching the videos first. Every single account of a good first attempt on this page has that step in it, and the one bad outcome quoted earlier does not.

11  The pick

Which one to buy.

If you are correcting whole cars, the answer is a 15mm machine, because that is the throw Adam's itself recommends for most customers. From there the only real question is whether you want the cable in the picture.

See the Cordless 15mm Swirl Killer Three configurations, from 569.99

If your paint is basically healthy and you want the same throw on a cable, the SK Pro 15mm is 259.99 with a detachable 25 foot cord and a built in polishing light, and several of the reviews above were written about it. If you already own a full size machine and keep running out of room around mirrors, pillars and badges, the Cordless 12mm at 449.99 is the companion, not the main tool.
