You remember the day you first held the key in your hand. We take your car back to that moment — and protect it. Paint correction. Precision detailing. Ceramic protection. Your car. Our undivided attention.
You feel the difference before you can explain it: when the reflection stands still and the paint has depth again. That is why every project starts with an assessment — and only ends when the light has nothing left to criticise.
In detailing, quality is measured by one thing: the clarity of the reflection.

Under a point light source, wash marks and swirls become visible — after correction, only the reflection remains. Drag the slider.
Real photographs from the workshop, documented under inspection lighting.
There is no button for perfection. There is only pass by pass, polish by polish, checked under the inspection lamp — until the reflection is right. On demanding projects that means two to three stages. And the patience to skip none of them.
It did not start with a company. It started with an obsession: cars — and the inability to accept a scratch that others could not even see. A bucket, polish and patience grew into a standard that got around.
Through this passion I met entrepreneurs early on who shared it. They entrusted me with their cars — and watched how the work was done: pass by pass, checked in the light, no shortcuts. It was not the result alone that convinced them. It was the way it came about.
Years later, with experience as a CFO and advisor, those same entrepreneurs remembered: whoever works on a car like this, works on everything like this. They brought me into their companies — to apply the same principles there: precision, honesty, no compromises.
And so one thing became the other. Two houses, one standard.
Today Joachim Kern advises companies at kern.lu — and cares for their cars here.
Every wash mark is a small reminder that someone was careless. We take them back — controlled, machine-polished, in exactly the number of stages the condition requires.
The feeling of getting into a perfectly detailed car never wears off. Exterior and interior, every surface treated correctly — until it feels like a handover again.
A car's best moment does not have to stay a moment. After full preparation, the ceramic system protects suitable surfaces — in the comprehensive package, glass and plastics as well as paint.
A motorcycle hides nothing — every bolt, every surface is exposed. That is exactly why we love this work: depth of detail in the tightest spaces, visible from every angle.
We could write a lot about quality. But reflections don't lie.
A light touch while parking. The uncoated car lost paint. The ceramic-protected one next to it: the marks polished out completely.
Ceramic-protected from day one — through rain, road salt and summer heat. Not a show car, but a daily driver in real life.
Only wash tunnels, the paint full of holograms and scratches. After a complete interior and exterior detail with ceramic coating, the question was no longer whether detailing a used car is worth it.
No recipe book — but a sequence proven on every vehicle.
Evaluation of paint condition, defects and materials — the basis for scope and quotation.
Thorough, gentle washing and decontamination as the foundation for all further work.
Machine polishing in as many stages as the condition demands — checked under inspection lighting.
Complete degreasing and inspection of every surface to be protected.
Ceramic protection for suitable surfaces — paint, glass, plastics, depending on the package.
Final inspection at the vehicle and practical care advice — so the result lasts.
Vehicle size, paint condition, desired level of correction and scope of protection differ from car to car. That is why there are no off-the-shelf flat rates — only a transparent quotation after assessment.
As a rule of thumb, a high-end coating project often equals about one percent of the car's value — protection for the other ninety-nine. And the paint is the one surface everyone sees, and the one you can never reorder.
