What happens if i damage my ceramic coating?
Quick answer: The damage is local, and so is the consequence. A ceramic coating sits on the paint panel by panel, a few microns thick, so a scratch, scuff or chip takes the coating with it in that spot and leaves the rest of the car exactly as it was. Mechanical damage is not a warranty claim, but it does not cancel your cover on the panels that were not touched. The paint is repaired the way it would be on any car, the panel is re-coated afterwards, and on an insurance job the re-coat can usually go on the claim.
This is one of the questions we get most often from owners who have just had a car coated, and it usually arrives with a slight note of worry behind it. I have spent money protecting this paint, so what happens the first time a trolley catches the door or a stone chips the bonnet? Have I made the car harder to repair? Have I locked myself into something? The short version is no. The damage is confined to where it happened, the rest of the coating carries on, and the panel goes back to coated once it has been put right. The repair itself, from the first pass of the polisher to the cure, has its own page: how can a damaged ceramic coating be repaired. This one is about what the damage means for you.
What the damage does, and what it does not
A cured ceramic coating is only a few microns thick: far thinner than the clear coat beneath it, and thinner than a sheet of paper by a wide margin. It bonds to each panel separately, so it is better pictured as a finish than as a shell. When something goes through it, the coating in that spot is gone and the mark you can see is in the paint. Everywhere else the coating is untouched and still doing its job; a keyed door does not change how the bonnet beads.
It also helps to be clear about what the coating was ever going to stop. It resists wash marks, chemical etching from bird droppings and tree sap, and the fine swirls a year of washing puts into unprotected lacquer. It is not armour. A stone at motorway speed, a key, or a trolley edge goes through a coating exactly as it goes through bare clear coat, which is why no coating warranty covers that kind of damage; the boundary is set out in what our ceramic coating guarantee covers. Part of the confusion comes from products sold as liquid ceramic paint, which is ceramic coating the same as liquid ceramic paint untangles.
Does it affect the guarantee?
Mechanical damage is not a claim, on ours or on the manufacturer's: nobody's warranty pays to repair a scratch. What it also is not is a reason to lose the cover you have. The guarantee is a promise about the coating we applied and the work underneath it, and a damaged panel does not undo that promise on the panels around it. Once the repaired panel has been re-coated by us it goes back into the record with the rest of the car; Tom photographs every car at booking-in and again after correction, so there is a dated picture of what was done and when. If the panel is repaired elsewhere, let us know which panel and what went on, so our record of the car stays accurate. The conditions that do apply, and why they are there, are in doesn't the small print mean the guarantee is worthless.
The rear door that did not become a whole car
A customer we had coated a dark metallic estate brought it back after someone reversed into the nearside rear door in a car park. Their worry was not the door; it was every other panel. They had assumed the whole car would have to be stripped and re-done to match. It did not. The body shop sprayed and blended the one door, it cured for a week, and we corrected and re-coated that single panel. Stood next to the panels we had originally done, you could not pick out which one had been redone, and the cover on the rest of the car carried on as if nothing had happened. One panel in, one panel out; the dread of a full re-do almost never matches what actually needs doing.
What to do on the day
Three things, none of them urgent. Photograph the damage before anything is done to it, in daylight, with something in the frame for scale. Leave it alone: whoever repairs it will want to see the mark as it is, and before you reach for a compound from the boot of the car, read can you buff out scratches on a ceramic coating. And tell whoever does the repair that the car is coated, whether that is a body shop, a mobile repairer or an insurer. For a stone chip rather than a scuffed panel, the practical question is can I touch up over a ceramic coating.
If the damage goes through insurance
When a panel is repaired or resprayed on an insurance claim (after a car park knock, say, or a more serious shunt), the cost of putting the coating back can usually be included. The repair is not finished until the panel is back to the condition it was in before the incident, and on a coated car that condition includes the coating. Coatings are an accepted part of a car's specification now, and a panel that was coated before the accident is reasonably restored to coated afterwards.
The thing that trips owners up is silence. If the insurer and the body shop are never told the car was coated, they will repair the paint and stop there, and you will be left paying to restore the protection. So say it early, in writing if you can: the vehicle is ceramic coated, and reinstating the coating on any repaired panel needs to be part of the work. A body shop that resprays without re-coating has not done anything wrong by their own scope; they simply were not asked. Raise it when the claim is set up and it tends to be straightforward; raise it after the fact and you may be the one absorbing the cost.
What it costs you
Outside insurance, re-coating a repaired panel is chargeable, because it is a genuine piece of work: preparation, correction, application and cure time, the same as any professional coating job on a smaller area. What it is not is a second full coating. You are paying for one panel's worth of prep and product, not the whole-car price you paid the first time, and when people brace for a big bill and hear the single-panel figure, the relief is usually visible.
What this means if you are keeping the car
For an owner planning to hold onto a car for years, the takeaway is reassuring. A ceramic coating does not make accidents more expensive to put right, it does not corner you into anything, and one bad day in a car park does not undo the protection on the rest of the car. Damage gets assessed and repaired exactly as it would on any uncoated car; the only addition is re-coating the area afterwards so the protection, and the cover, is continuous again.
