Insurance & Repair
A ceramic coating is a sacrificial layer of cured glass-like chemistry sitting on top of the clear coat. As soon as a panel is resprayed, sanded or flatted back by a body shop, that layer is gone on whatever panel has been worked on, which is why insurance and repair work are worth thinking about as a single topic, rather than three separate questions.
This section covers what happens to the coating when a car is damaged, how long after a repair and repaint we can coat a fresh panel, and whether a cosmetic touch-up can be done over the top of an existing coating. The honest short version: we can almost always put you back where you started, but the timing, the panel count and the insurer's scope of works all change what that costs and how long it takes.
What happens to the coating when a panel is damaged
A coating does not make paint invincible. It adds gloss, makes washing easier, and shrugs off light scratches that would otherwise mark the clear coat, but a car park dent, a trolley strike or a proper stone chip will still go through it. Once the panel is refinished, the coating on that panel is lost: the body shop flats the area, blends the paint and applies new lacquer, and there is nothing left for the coating to sit on.
Coatings on the surrounding panels are normally unaffected, so in most insurance claims we are recoating one or two panels rather than the whole car. The questions below go through the three scenarios customers ask about most.
It helps to be clear about what actually fails when a panel is damaged. A coating is bonded to the clear coat at a molecular level; it is not a film you can peel and replace. When a body shop preps a panel, the first thing they do is flat it back with abrasive paper, typically P400 to P800 to key the surface, then finer grades to feather the edges of the repair. That process removes the coating, the lacquer it was sitting on and a few microns of the colour coat underneath. There is no way to mask the coating off and put it back: the moment the panel is keyed, the chemistry is gone. This is why we never talk about "repairing" a coating on a damaged panel. We strip what little remains, let the new paint settle, and apply a fresh coating to the refinished surface.
The three questions customers ask
- What happens if I damage my ceramic coating?: what the coating does and does not protect against, and what we can do for the affected panel once it has been repaired.
- How long after a respray before I can have my car ceramic coated?: the respray waiting period and why we will not coat fresh paint until it has fully cured and out-gassed.
- Can I touch up over a ceramic coating?: what a panel-level coating repair or rework involves when we do it for existing customers.
Why fresh paint cannot be coated straight away
The most common misunderstanding we see is timing. A customer collects the car from the body shop on Friday, the paint looks perfect, and they want it coated on Monday. We will not do it, and the reason is chemistry rather than caution.
Modern refinish paint is applied wet and cured in a low-bake oven, usually around 60 degrees C for forty to sixty minutes. That bake makes the panel touch-dry and hard enough to handle, but it does not finish the job. Underneath the surface the paint and lacquer are still off-gassing, releasing solvents that worked their way through the film while it cured. A ceramic coating forms a near-impermeable barrier once it crosslinks, and if you seal that barrier over paint that is still venting solvent, you trap the gas underneath. The result, weeks later, is micro-blistering, a hazy bloom, or a coating that simply will not bond and starts lifting at the edges.
Our standard is to leave a refinished panel for a minimum of four to six weeks before coating, and we will not coat sooner even if the customer pushes. Tom, our operations manager, keeps the body-shop completion date on the job sheet for exactly this reason: he books the recoat from the date the paint left the oven, not the date the car was returned to the customer. If the body shop has air-dried rather than baked the panel, we extend the window further, because air-dried refinish can take considerably longer to stabilise.
How insurance work fits in
If your car is booked in for repair through an insurer, the body shop's scope of works will not include reapplying the coating; that is not something most body shops offer, and it is not part of a standard claim. What we usually do is wait until the repair is finished and the paint has cured, then bring the car back in for a panel-level recoat. It is a smaller job than the original coating, because only the worked panels need treating, and the surrounding paintwork stays as it was.
Whether your insurer will cover the recoat depends on your policy and how the coating was declared at the point of sale. If you are unsure, it is worth asking before the car goes in for repair; we are happy to provide a quote in writing to support a claim.
Matching the recoat to the rest of the car
A panel-level recoat is not just about protection; it has to look right next to panels that have been coated and weathered for a year or two. A fresh coating sits slightly higher in gloss and slickness than an aged one, so a single recoated wing can look subtly different under the right light. Where the original coating product is known (and on our own jobs it is, because we record the product on the file), we recoat with the same chemistry. If the car was coated elsewhere with an unknown product, we will often lightly refresh the adjacent panels at the same time so the transition is invisible. This matters most on metallics and dark solids, where the difference in reflectivity is easiest to spot.
Blending and the edge of the repair
Body shops rarely respray a whole panel for a small repair; they blend the new colour into the existing paint partway across the panel to avoid a visible colour step. That blend zone is the part of the repair most worth watching. The new lacquer feathers out across an area that still carries the old coating, and we have to decide where the new coating should start and stop. Our usual approach is to coat the full repaired panel rather than chase the blend line, because a coating boundary mid-panel is harder to hide than a clean panel-edge transition at a shut line.
What a coating does and does not survive
It is worth setting expectations on the kind of damage a coating actually deals with, because the answer shapes whether you are looking at a wash, a paintwork correction, or a full repair and recoat.
A coating handles the things that mark soft clear coat: bird-lime etching if it is rinsed off reasonably promptly, light wash marring, road film and the kind of fine swirls that come from poor washing technique. It buys you time on bird droppings and tree sap because the surface is harder and far less porous than bare lacquer, but it is not immune; left baking on a hot panel for days, acidic contamination will still etch through. What a coating will never do is stop physical impact. A stone chip, a key scratch that reaches the colour coat, a kerbed bumper or a trolley dent are all body-shop jobs. The coating in those areas is collateral damage, and recoating is the last step once the structural and paint repair is done.
Between those two extremes sits the grey area customers ask about most: a scuff that has gone through the coating and into the lacquer but not to the colour. Sometimes that polishes out, and where it does we can correct and recoat the single panel without involving a body shop at all. Whether it polishes out depends on how deep the mark is, and you can only know by measuring; that is the next point.
How we assess a damaged coated car
When a coated car comes in after damage, the first tool out is the paint depth gauge, not the polisher. A healthy modern clear coat runs somewhere around 40 to 60 microns over the colour and primer. We take readings across the affected panel and compare them to an undamaged panel on the same car. If the reading is low (because a previous owner or repairer has already flatted and polished that area hard), there may not be enough lacquer left to safely correct a scuff, and the honest answer is that the panel needs refinishing rather than machining. Pushing a polisher through thin lacquer to chase a scratch is how you burn through to colour, and that turns a small job into a respray.
This is also where we are candid with people about cost. If a mark will polish out of healthy lacquer and recoat for a fraction of a respray, we say so. If the lacquer is too thin or the damage is too deep, we say that too, and point them at the right repair before any coating work. There is no sense coating a panel that is going to need spraying in six months.

The takeaway for anyone landing here after a knock or a claim: nothing about a damaged coating is unrecoverable. Get the repair done properly, let the paint cure, and the affected panels can be brought back to match.
