Our Guide to Car Body Repairs

19 September 2018 Concept Car

Thanks to technological innovations and progress in materials, modern cars can last a very long time. Unfortunately, this does not protect you against wear and tear or accidents. Car body repairs particularly are among the most frequent sources of problems. Sometimes, they merely involve a tiny scratch. At other times, they can amount to deep dents and extensive paint jobs. Regardless, you’re sure to run into one of these repairs sooner or later.

And when you do, it helps to be prepared.

If you’re in need of a car body repair of one sort or the other, this guide will help you find the best solution – from what to look for in a mechanic to which repairs to perform on your own.

Ready to take things into your own hands? Here’s how.

Car Body Repairs – are they still relevant?

Car body repairs were long the most common reason to visit a car body shop. In fact, solidity and ruggedness were among the most important quality criteria for a car. For decades, Italian manufacturers were plagued by accusations that their cars were subject to rust, for example. This severely tarnished their image.

Today, as automobiles have become more electrical, most repairs are performed on the wiring and the digital components. Engine-related issues also rank high in the repair statistics.

In comparison, major improvements in steel, paint and glass have significantly brought the number of car body repairs down.

Despite these facts, we’ll make a daring claim:

Car body repairs are more relevant today than ever!

As always, blame it on the Internet. Thanks to excellent websites and self help guides, more and more drivers feel confident enough to handle car body repairs themselves.

Investigating whether or not this is a good thing is part of the motivation behind this article. One thing’s for sure, though: Thanks to the boost in confidence and most importantly knowledge, mechanics can no longer sell customers repairs that are unnecessary, not good enough or even unprofessional. Charging massively overblown prices has also become rare.

It’s hard to argue with these benefits. However, we have to point out the following:

Fixing things yourself also comes with its dangers

For one, you’ll need at least a bit of experience to really pull some of these car body repairs off. Even sanding a paint surface for optimum results is not as easy as it looks. Unless you have done this before, getting the pressure and angle just right and knowing what the result should look like are anything but trivial. And if you should fail, there’s every danger that you’ll end up making things worse.

Another danger is that the repair is simply too complex. Disassembling and re-assembling components, re-wiring electrical devices or working with delicate materials can all end in disaster. As The Humble Mechanic has rightly pointed out in one of his recent podcast episodes, even something as ordinary as exchanging a car radio can cause problems because of the complexity of the wiring involved.

Granted: If you take your car to a mechanic, they, too, can mess things up. But at least in that case, your warranty will protect you. This doesn’t apply when using your own two hands.

Although we strongly support the empowerment movement in car body repairs, there are a few repairs you should never perform yourself.

Whatever you do, never do these #1: Replacing the windshield

If you’ve ever seen a mechanic replace a windshield, you may have been surprised by how easy it looks. And indeed, when performed by an experienced expert, even replacing larger windshields can be a matter of a few minutes.

Don’t let this fool you, however. This task requires a delicate touch and exact knowledge of the right angles. These shields are extremely heavy, too. You wouldn’t be the first to literally see your own repair go up in shards.

Whatever you do, never do these #2: Large-area paint jobs or big dents

As we’ll explain later in this article, paint jobs and dents are among the car body repairs that you can perform yourself. That, however, doesn’t mean that you can perform all of them yourself.

If you need to re-do larger areas of the paint surface if the scratch is very deep or if you have large dents in the body, we strongly suggest you get these repaired by an expert. Unless you’re a natural talent, the danger of dissatisfying results is just too big.

Whatever you do, never do these #3: Unseen Frame and Alignment Damage

Alignment problems are very literally damages to the body of the car. They may not be visible to the naked eye. But if you experience your car being pulled to the left or right while driving, this is a sure sign of an alignment issue.

These repairs also require expertise and specialised equipment to be performed successfully. And since a failed repair puts you in danger of an accident, we strongly advise against even trying these for yourself.

Whatever you do, never do these #4: Removing Rust

On paper, rust and paint should be very similar to treat. In practise, rust tends to be a whole lot harder to beat. As Orlando Auto Body write in an informative blog entry, a simple scrub is not enough, because rust tends to be deep-seated.

Even if you do manage to remove all of the visible rust, it tends to come back. This is because there is usually a lot of ‘invisible’ rust, and only an expert with the necessary experience is able to spot it.

All of this would hardly amount to much, if rust weren’t such a major issue.

New cars experience far less rust issues than older models. If rust does rear its ugly head, however, you need to act swiftly and with precision. This is why this type of car body repair is better left to a professional.

The right car body shop: Whom to trust?

Let’s say you have a repair that definitely needs to be performed by a trained technician. Whom should you turn to?

This is not a simple question by any means. Although the Internet has made it easier for dissatisfied customers to voice their opinion, not all online ratings are realistic or fair. They tend to over-represent honest negative opinions and frequently feature fake positive feedback. As a result, it is anything but easy to arrive at satisfying conclusions about what makes for a good place to get car body repairs done.

This is why car platform Edmunds even recommends paying attention to word of mouth and listening to recommendations from friends and family. These are actual reports by people you know and trust. Plus, you’ll be able to ask questions as well.

Questions, questions, questions

Asking ‘the right questions’ may well be the most important part of getting your car repaired. In an expansive article, website carwise provides for a long list of useful conversation starters:

  • What is the warranty like? How long does it last and what, exactly, does it cover? As a general rule, you should never trust life-time warranties, as these tend to have impossible to meet conditions.
  • If your car needs to remain at the mechanic for one or more days, is there a possibility to get a rental car as a replacement?
  • Can you take pictures of my car before I hand it in for repair? A professional shop should not object to this.
  • How long will the repair take? Be prepared to wait – the average repair time currently stands at almost 10 days. This need not be a bad sign. In fact, as the Huffington Post suggests, heavy traffic can be an indicator of excellence.
  • Do you have the exact paint to match the current vehicle colour?
  • What kind of parts will the shop use? As autoblog.com write, this is an area where you should tread carefully: “While used parts were made by your vehicle manufacturer and perform as well as new original parts, aftermarket parts are often cheap imitations with inferior quality. These parts can corrode, rattle and ultimately diminish your car’s value.”

Car Body Repairs you can perform yourself #1: Paint Jobs

Smaller paint jobs do require a bit of a good eye and secure hand. But you can definitely perform these yourself. What you’ll need:

  • The exact same colour the manufacturer used. You can find the colour code in the user’s manual.
  • A garage with good light conditions. Why? Simple: Because you need to be able to see what you’re doing.
  • A compressor and a paint sprayer. A brush may be okay when renovating your house. For a car, however, only a sprayer can yield the consistency you need for optimal results.
  • Protective clothing. This especially includes protection against toxic paint fumes.
  • Very fine sandpaper. Experts recommend starting with 400-grit paper and finishing off with 800-grit.

Paint jobs: How to do it

Painting over a scratch isn’t rocket science. What it requires is mainly a steady hand and a lot of patience. Especially if the scratch is deep and you can already see the primer, you will need to apply several layers of paint over the course of a few days.

At the end of the process, use the fine sandpaper to get the area as smooth as possible – only then won’t you notice the work. Work carefully and without applying too much pressure. It may take forever, but it is usually worth it.

Car Body Repairs you can perform yourself #2: Dents

In terms of their impact on your car’s look, dents may be worse than scratches. They can make even an all but new vehicle look like a piece of junk you picked up from the scrapyard.

Thankfully, there are plenty of simple DIY car body repair tips to pop these dents out again. We’ve compiled some of the most creative solutions for you. For a full list, visit this website for even more suggestions:

  • The Plunger: This one may seem a bit brutish. But using a plunger makes absolute sense for car dents. The basic principle is similar to unclogging your toilet: By creating a vacuum and applying just a little bit of force, you can suck the dent back. This method only works for smaller dents. But it is among the most effective and easiest around.
  • Hands and Boiling Water: If only you could simply pop out those nasty dents in your bumper by hand. Well, you may just be able to do that! Apply hot water to the front side of the bumper. This will make the plastic softer and more malleable. Then, reach behind the bumper. If all goes well, you should now be able to pop the dent back in.
  • Hairdryer & Compressed Air. The hairdryer technique for dents would have to be an urban legend – if it weren’t true! Use the hairdryer to heat up the dent area, then apply a can of compressed air to cool it right down again. Because of the sudden temperature differential, the dent should come popping out again.
