What decides car denting and painting cost in Chennai?

I started as a denter at the age of 10 and opened my own garage at 19. Over 37 years, our garage in Mylapore has worked on 5000+ cars, from small hatchbacks to Jaguar, BMW, Benz and BYD. This post explains how a denting and painting price is worked out, so you can read any garage's estimate with more confidence.

I am not putting prices in this article. Paint, primer and labour costs change, and a price printed on a blog page goes out of date. What does not change is the list of things that make one repair cost more than another. Once you know that list, you can look at your own dent and roughly guess which end of the range it will fall in.

Why can't a garage quote a fixed price over the phone?

A phone call gives the garage a description, and two dents described the same way can need very different work. "A small dent on the door" could be a shallow ding that pops back out with the paint intact. It could also be a sharp crease on the body line where the metal has stretched and the paint has cracked. The first might only need a few minutes of work and a polish. The second needs pulling, shaping, a thin layer of filler, primer, paint, clear coat and blending into the next panel.

A photo helps a lot, which is why we ask customers to WhatsApp one. A clear photo usually shows whether the paint has cracked, roughly how deep the dent is and whether it crosses a body line. What a photo cannot show is damage behind the panel, such as a bent inner bracket or a broken clip. That is why the written estimate comes after we see the car.

What makes a dent cheap or expensive to fix?

The denting part of the bill is mostly labour. It depends on how long it takes to bring the metal back to its original shape. Four things decide that.

Size and depth

A wide, shallow dent is usually easier than a small, deep one. In a shallow dent the metal has bent but not stretched, so it can often be worked back into place. A deep, sharp dent pushes the metal past the point where it springs back. Stretched metal has more surface area than it started with, and the extra has to be shrunk or shaped before the panel is flat again.

Where the dent sits

Dents in the middle of a flat door are the simplest. Dents on a body line, the sharp crease that runs along the side of most cars, take much longer, because the line has to be restored to a crisp edge that matches the rest of the car. Dents near the edge of a panel, around the fuel lid or close to a door handle are also slower, because there is less room to work and the metal is stiffer.

Access from behind

The cleanest way to remove a dent is to push it out from behind the panel. On doors this often means removing the inner trim. On a quarter panel or roof there may be no easy way to reach the back, so the dent has to be pulled from the front using pulling tools. Removing trim, lining or lamps adds time to the job, and that time shows up on the estimate.

Cracked paint and rust

If the paint over the dent has cracked, the job is no longer just denting. The panel will need paint, and if the crack has been open for a while, moisture may have started rust on the bare metal. Rust has to be ground off and treated before primer goes on. This is the main reason I tell people not to leave a cracked dent for months.

What drives the painting part of the cost?

Painting is where materials start to matter. Primer, base colour and clear coat all cost money, and the amount used depends on how much area is being painted. These are the factors that move the painting part of the bill.

Number of panels

Each panel is prepared, masked, painted and finished separately, so two panels cost roughly twice the work of one. A scrape that runs across a front door and a rear door counts as two panels, even if it looks like one scratch.

Type of colour

Solid colours, like plain white or plain red, are the most forgiving to match. Metallic and pearl colours contain tiny flakes that reflect light. To look right, the flakes in the new paint have to settle at the same angle as the flakes in the original paint. Getting that right takes more skill and more material, and it is the main reason metallic colours are usually blended into the next panel.

Blending

Blending means fading the new colour into the panel next to the repair, so the edge where new paint meets old is hard to find. We blend into the next panel at our garage, and we tell the customer before we do it, because it adds time and material. Without blending, a repaired door can look slightly different from the fender beside it when you see the car in sunlight, even if the colour code is correct. Paint on a car ages in the sun, so a 5-year-old panel is rarely the same shade it was when new.

Plastic bumpers and metal panels

Most modern bumpers are plastic. Plastic needs a different primer so the paint grips, and a bumper that has cracked may need plastic welding before it can be painted. Bumpers with parking sensors take extra care, because the sensors must be removed, masked or painted without affecting how they work.

Does the car brand change the price?

Sometimes. The dent itself does not know which badge is on the bonnet, but a few brand-related things can affect cost. Some luxury cars use aluminium panels in places, which behave differently from steel and take more care to shape. Some colours on premium cars are three-layer paints that need more steps. Cars with sensors and cameras in the bumpers need those parts handled carefully during the job.

Our garage has worked on Jaguar, BMW, Benz and BYD cars as part of the 5000+ cars we have handled, alongside everyday hatchbacks and sedans. The process in the paint booth is the same for all of them. What changes is the time some steps take.

When is polishing enough?

Not every mark needs paint, and a garage that paints everything will cost you more than necessary. Run a fingernail across a scratch. If your nail glides over it, the scratch is probably only in the clear coat, the transparent top layer, and polishing may remove it. If your nail catches, the scratch has gone through the clear coat into the colour or deeper, and that area will need paint.

If a scratch only needs polishing, we tell the customer so and polish it. That is a much smaller bill, and it keeps more of the original factory paint on the car. We wrote a longer guide on this: how to tell if a car scratch needs repainting.

What should a written estimate include?

A written estimate protects both sides. At Yours Automobile, you get one before any work starts, and nothing outside it is done without your okay. Whichever garage you use, a good estimate should list:

• Each panel that will be worked on, by name
• Whether each panel needs denting, painting or both
• Whether the new paint will be blended into neighbouring panels
• Any parts to be replaced, such as clips, trims or a cracked bumper
• Any extra work you asked for, such as servicing or a wash
• The total price and the day the car will be ready

If an estimate only says "body work" with one number, ask what it covers. Two estimates can only be compared fairly if they describe the same repair.

Why do two garages quote different prices for the same dent?

Usually because they are planning different repairs. One garage may plan to pull the metal back and use a thin skim of filler, while another plans to fill the dent with a thick layer and sand it flat. Thick filler is faster and cheaper on the day, but it can crack or shrink later and show the outline of the old dent. One garage may blend into the next panel, and another may paint only the damaged panel and leave a visible edge.

I would rather explain the method and the price together, so the customer can decide. At our garage that means a written estimate before any work starts, and nothing outside it without your okay.

How can you keep the cost down?

A few habits help, and none of them involve cutting corners on the repair itself.

• Fix cracked paint early. Bare metal starts to rust once moisture gets in, especially during the monsoon. Rust treatment adds work.
• Send a clear photo first. A daylight photo from a few steps back and one close-up let the garage tell you early whether polishing might be enough.
• Avoid DIY filler. Home filler kits often leave a layer that has to be ground off before a proper repair can start.
• Combine jobs. If two panels need work, doing them together is less work than two separate visits, because the car is masked and in the booth once.
• Ask about blending. Blending costs a little more, but it can save you from a repair that looks patchy and needs redoing.

What about dealers and resellers?

Car dealers and resellers preparing stock cars for sale have different cost questions. They usually want to know which repairs will make the biggest difference to how the car looks to a buyer. For a used car, removing visible dents on doors and bumpers and detailing the paint and interior often matters more than repainting minor marks on the roof. We write the estimate panel by panel, so the dealer can decide what to include.

Company fleets can also book scheduled body checks, which catch small damage before it grows into a bigger bill. You can read more on the services page.
