You hear the bang before you feel it. Then you’re out on the road, staring at the door and telling yourself it could be worse. A dent, a few scratches, maybe a crease along the side.
Fair enough. But if that door drags on the pillar, or one panel sits a touch proud of its neighbour, the hit has gone deeper than the paint. What you can see is usually only half the story.
That’s where professional panel beating earns its keep. A good panel beater works out what’s actually damaged, fixes or replaces it, and gets the paint looking right again. If you’re a Kiwi driver picking a repairer, that choice decides how the car looks and how long the repair lasts.
So, here’s how a repair really runs, start to finish, so you know what to ask when you walk in.
Someone’s car, a pole, or a concrete wall meets the side of yours. That’s a side impact. Most happen at intersections, in supermarket car parks or when another driver drifts into your lane. And sometimes a driver just misjudges the gap.
How much damage you end up with comes down to speed, angle, and where the other thing hit you. A slow bump might leave a shallow dent in a door. A harder one takes out a few panels and pushes into the structure behind them.
Here’s what to look for:
Even if it looks cosmetic, get it checked. Modern cars have reinforced body structures, wiring, and safety systems running through the sides. Good car body repairs deal with the damage that’s actually there, not just the bit that spoils the look.
Everything starts with a good look over the car.
The panel beater goes over the damaged doors, side panels and wheel arches, then the bodywork around them. They check the hinges, locks and window mechanisms too, along with any panels next to the hit.
After a harder impact, they’ll check whether the structure has moved. Measuring equipment picks up distortion your eyes won’t. A pillar can be a few millimetres out and look perfectly fine from a metre away.
From there, the repairer decides whether a panel can be reshaped or needs replacing. That call depends on how bad the damage is, what the panel’s made from, and what the manufacturer says about repairing it.
The plan also gives you a likely cost and timeframe. But sometimes extra damage only shows up once the door card comes off or the panel’s removed. If that happens, they should tell you what they’ve found and talk through any change to the estimate before carrying on.
Once the inspection’s done, the real panel beating starts.
When a dent’s repairable, the technician works the metal back into shape with specialised tools, a little at a time. The aim is to bring the dent out without harming the metal around it.
Small dents are fairly quick. Deeper creases and bigger areas take a lot more work. The panel beater rebuilds the contours so the repaired spot follows the car’s original lines.
Some doors are past saving. If one’s crushed or torn, or the damage is too severe to repair, a replacement is the smarter move.
The material matters as well. Steel and aluminium need different repair techniques, and some newer components have strict limits on how they can be repaired at all.
With car panel repair, the shape has to be right, and the repair has to suit how that part of the car is built. Get that sorted and you won’t be able to pick the repaired spot from the rest of the bodywork.
A side hit can shift the way a door sits against the body. A few millimetres is enough. You get uneven gaps, a door you have to slam, or a lock that won’t catch.
Smash repairs always include a check of the doors and the panels beside them. The technician adjusts hinges where that’s what’s needed, then confirms the doors open, close, and latch the way they should.
Bigger accidents can reach the door pillars and side sills. Those parts hold the car’s strength and protect the people inside, so they get serious attention.
If there’s structural damage, the repair follows the manufacturer’s procedures. Depending on the car and the hit, that can mean measuring and straightening equipment.
They’ll also look at wiring, window regulators, and door locks. If the crash has affected the airbags or other restraint components, that gets sorted before the car goes back on the road. No exceptions.
Plenty of cars look fine from the outside and still have a door that’s out of line or a lock that plays up. Good panel beating looks at both.
Once the panel’s repaired or replaced, the focus moves to the surface.
Paint prep is where a lot of the final result is won or lost. Rough edges, low spots, and leftover marks all show up once the new paint goes on. And they show up worse in sunlight than they ever do in the shed.
The technician sands the repaired area smooth and strips back any damaged paint. Filler goes on where small imperfections need levelling, then it’s sanded again.
Next, the surface is cleaned and primed for the paint system being used. Then out come the masking tape and paper. Windows, trims, and any undamaged paint get covered so the overspray stays off them.
Prep is what makes the paint stick and gives the top coats a flat, even base. Skip corners here and the finish goes patchy, or the paint lifts or fails early. It’s a big reason to go to an experienced shop instead of someone offering a quick cosmetic fix.
Matching the paint is one of the trickiest parts of any collision job.
Your car’s paint has sat in the sun and rain for years, and the colour’s shifted a little. So even with the factory paint code, fresh paint can look a shade off next to the old panels.
The painter starts with the paint code and a colour-matching system, then leans on experience to pick the closest colour. Depending on the finish and the size of the repair, they may blend the new paint into the neighbouring panels so there’s no hard line where new meets old.
After that it’s primer, then basecoat, then clearcoat. Each layer goes on evenly and gets left to cure for as long as it needs.
Metallic and pearl paints are the fussy ones. They change with the light and the angle you’re looking from, so careful application matters to stop the repair from standing out against the original paint.
The job isn’t finished when the paint dries. Before you collect the car, the repairer should run through final checks.
Anything that came off goes back on: door handles, mirrors, trims, interior panels. Then the technician tests the doors, windows, locks, and anything else the repairer touched.
They check the repaired panels for alignment, even gaps, and paint quality. Where the car has safety systems or driver assistance features, those may need testing or calibration to the manufacturer’s procedures.
If the hit affected sensors or wiring, those checks happen before the car goes back to you.
These last checks pick up the little things that get missed. They also confirm the finished work matches what was agreed. And a decent repair covers everything found during the assessment, not only the bits you can see.
The cost of car accident repair in New Zealand depends on how hard the hit was and how many parts it took out.
One shallow dent in a door is usually a straightforward fix. But multiple panels, structural damage, replacement parts, and repainting add up to a lot more work.
Other things that move the price:
Insurance affects things too, including how much you pay. Planning to claim? Check your policy first and talk to your insurer before you sign off on any work. If you’ve got questions about how the claim side works, ask us.
Get the estimate in writing, so you know what’s being fixed and what you’re likely to pay. And ask how they’ll handle extra damage if they find more once the job’s underway.
Choosing who does the work matters just as much as knowing how it’s done. We’ve also put together a guide to choosing a panel beater in Christchurch if you want more on that.
You want a shop that does collision work day in, day out, has the right gear and knows how modern cars go together. Ask how they’ll assess the damage and whether panels will be repaired or replaced. And find out what gets checked before the car comes back to you.
Talk about the timeframe, the paintwork warranty, and anything your insurer needs from them as well.
Don’t pick on price alone. A cheap quote might leave out repairs the car needs, while a detailed estimate shows you what the job really involves.
A good repairer explains things in plain language and tells you why they’re recommending each repair. If they can’t, ask them to show you.
Side-impact damage is a pain, especially when you need the car for work, the kids, and everything else. But the right repair gets it looking good again and deals with what the inspection turned up.
