Paint correction, not concealment

Almost every car on the road carries them. Fine circular scratches in the clear coat that scatter light in every direction instead of reflecting it cleanly, which is what makes paint look flat, hazy and grey rather than deep.

They are worst on dark colours, not because dark paint scratches more easily but because the contrast between the scratch and the surrounding paint is far higher. The same swirls on silver are nearly invisible.

They come from washing. Automatic car washes with spinning brushes are the worst offender, but a dirty wash mitt, a single bucket, or drying with the wrong towel will all do it. Every contact with the paint is an opportunity to put more in.

New cars arrive with them too, from transport, dealer washing and lot preparation. Catching that before the first wash is the whole point of new car protection. Very few leave a dealership genuinely defect-free, which surprises people who have just spent sixty thousand dollars.

A scratch is a valley in the clear coat. There are only two ways to make it disappear: fill the valley, or lower the surrounding surface until it is level with the bottom of it.

Filling is what glazes and filler-heavy polishes do. It looks identical on the day and it washes out within weeks, at which point the swirls are back and you have paid for nothing.

Correction does the second thing. A machine polisher with an abrasive compound removes a microscopic amount of clear coat across the panel until the surface is level again. The scratch is not hidden, it is gone, because the paint around it has come down to meet it.

That is why correction changes the colour so dramatically rather than just adding shine. Light finally has a flat surface to reflect off, so it comes back as a defined image instead of scattering. On black paint the difference is startling. See finished cars from the studio.

Stages are polishing passes. Each one is more labour, and more labour is most of what you are paying for.

Three stage and concours

For show cars, dark paint held to a very high standard, or heavily neglected finishes. Additional cutting and refining steps chase the last few percent of defect removal, and the time involved rises steeply for a difference most people would struggle to see in daylight.

The refining step matters more than people expect. Cutting alone leaves its own very fine haze behind, which is why a job that stops after the cut can look impressive under fluorescent light and disappointing in the sun.

One hundred percent correction is rarely the goal and is often the wrong goal.

A scratch that has gone through the clear coat into the colour or the primer cannot be polished out at all. There is nothing left to level. Those are a repair job rather than a polish — see what can and cannot be polished out. Chasing it means removing clear coat that is protecting the paint underneath, and past a certain point you burn through and the panel needs respraying.

The quick test at home: run a fingernail lightly across the scratch. If your nail does not catch, there is a good chance it can be corrected. If it catches, it needs filling and paint rather than polish, and any detailer telling you otherwise is about to damage your car.

We will tell you what is achievable on your specific paint before starting, and we would rather agree on ninety percent that is safe than promise a hundred that is not.

Clear coat is finite and it does not grow back. A factory panel carries a limited thickness of it, and every correction in that panel’s life uses some.

We take depth readings across the car before committing to an approach. Thin readings change the plan: a panel that has already been corrected twice, or resprayed badly, may only tolerate a light single stage where the rest of the car could take two.

Readings also reveal previous repairs. A panel reading dramatically thicker than its neighbours has almost certainly been resprayed, which is useful to know if you are buying the car and were not told about it.

Then we run test sections to find the least aggressive combination of pad and compound that actually achieves the result, rather than reaching for the hardest cut available and hoping.

Corrected paint is bare and unprotected. Every panel gets wiped down to strip polishing oils, which matters more than it sounds: skip it and any coating bonds to residue instead of to paint, which is why some coatings fail within months while the same product on the next car lasts years.

Then protection goes on. A sealant is the simpler option. A ceramic or graphene coating is the one that holds the result for years, and it is the natural pairing because correction is the expensive part and a coating is what stops you needing it again.

The washing that follows decides everything from there. Automatic brush washes will put swirls straight back into freshly corrected paint within a handful of visits, which is a fast way to waste what you just paid for. How to wash it properly covers the rest.

The order is not negotiable, and most of the time is spent before a machine touches the car.
