DIY dent remover: scrap or a real smart repair alternative?

Dents in the sheet metal are annoying – removing them is not exactly cheap, even with Smart Repair. But are DIY dent removal tools really an alternative? AUTO BILD wanted to know and has tested four DIY dent remover tools!

Regardless of whether it is a hailstorm, a careless car park neighbor or a mishap – once the dent is in the sheet metal, it is often not that easy to remove. Even repairs using the smart repair process are time-consuming and correspondingly expensive. So it can happen that several hundred euros have to be paid for removing a small dent. One or the other motorist comes to think about whether you could remove the dent yourself – after all, the Internet is full of DIY dent removal tools. But can something like that work at all? Or is it just doing more damage? AUTO BILD has tested four DIY dent removers!

Dent removal tools in the test: Pay attention to this

Even if you mean it colloquially, dents and bumps are not the same thing. The word “dent” describes the damage to the body caused by pressure on the body part. So a dent is a depression. A bump, on the other hand, is a bump in the body part, similar to a bump that you get if you bump your head. It is important to know whether you want to remove a dent or a dent in the body, because the work step depends on it. While a dent is usually pulled out of the sheet metal, a dent must be carefully pushed back. All tools could be used to remove both dents and dents.

But be careful: Not all dents or bumps can be removed with the tools – at least if you want to avoid damage to the paintwork. Removing dents or dents with sharp creases almost always results in paint damage. It can also happen on repainted components that the paint flakes off when the dent is removed; The same applies if cracks can be seen in the paint. In all these cases, dent removal should be left to a professional to avoid annoying and expensive consequential damage. The DIY dent removal tools can only be used on dents or dents on smooth body panels.

An overview of the dent removal tools

The test field consists of four sets of dent removal tools from the brands Randalfy, Manelord, Quixx and Presto. In addition, there are a few suction cups from Amazon, which are also offered as dent removal tools. With prices between 14.90 and 58.99 euros, all tools are well below the price of removing dents using smart repairs. With the exception of the suction cups, each dent removal tool set includes a hot glue gun, a pair of hot glue sticks, pull buttons and a device for pulling out the dents. While it works with a lever construction at Randalfy, Presto, Quixx and Manelord each use a rotary pulling tool. The Manelord tool set also includes a pull hammer, which was not included in the assessment – but more on that later.

Use of the dent removal tools

The adhesive bond between the sheet metal and the pull knob is crucial for removing dents. Important: clean and degrease the sheet metal beforehand!

The dent remover sets from Randalfy, Manelord, Quixx and Presto work on the same principle: the hot glue gun is filled with an adhesive stick and connected to the electricity. While the hot glue gun heats up, It is important to clean the body part thoroughly and also to degrease it (e.g. with brake cleaner) so that the adhesive adheres well. If the glue is hot enough, it is applied to a suitable pull button, which is then glued to the center of the dent. Then the glue has to harden for a few minutes. After the short waiting time, the pulling tool is put on. With the Randalfy tool, the dent is pulled using the lever tool, with the Quixx, Presto and Manelord using the rotary pulling tool. You should be careful not to pull the dent too much – otherwise the dent will turn into a bump. With all dent removal tools, however, it is very difficult to tell when the right time to stop is, you need enough patience and a sure instinct. To remove dents, you can press with the pull button from Presto and Quixx with the pull button mounted, Manelord and Randalfy each have a small rubber mallet with a rubber tapping tool.

The adhesive bond was not strong enough for the pull hammer from the Manelord set: the pull button tore off due to the sudden jerk, without having changed the dent in any way. The rotary pulling tool worked better: the glue held very well here and the dent could be pulled out. However, there was a slight risk of injury here, because the adhesive came off very abruptly and caused the rotary pulling tool to jump up. There was no risk of injury with the Randalfy lever tool, the dent was pulled out here too, the same applies to the Presto and Quixx sets. Only the result of the Quixx set was very disappointing: Although the adhesive connection was extremely stable (the pull button was difficult to remove), the twisting tool bent when it was tightened rather than removing the dent – a shame! Positive: All adhesive residues could be removed easily and without leaving any residue, no tools left permanent paint damage.

Test winner: the best dent removal tool

The mobile dent removal system from Presto offers the best support surface of all tested dent removal tools.

With 102 out of 130 possible points, the mobile dent removal system from Presto is the test winner. The content of the set is very clear: a hot glue gun, a few bars of hot glue, a pull knob with a diameter of 15 millimeters, a pull knob with a diameter of 20 millimeters and a rather cheap-looking rotary pulling tool are included in the set. But even if the rotary pulling tool looks rather cheap, it works much better than the tools of the colleagues. While the pulling tool of the competition only has two contact points where a lot of force acts on the body part, the rotary pulling tool from Presto distributes the force more evenly and gently around the dent over a round contact surface.

  • simple application
  • large contact surface
  • small dent almost gone
  • big dent much better
  • Glue residue can be easily removed

14.90

The small dent was removed well the first time and hardly needed any rework; the large dent required some rework, but a good result could be achieved with patience. The only disadvantage: the hot glue gun is operated via the car’s cigarette lighter. Operation via a conventional 230-volt socket would be better here, nobody has to suddenly remove a dent while on the move. It is useful for screwdrivers without their own power connection on the car, but then a slightly longer cable would be necessary. But the result is convincing, and at 14.90 euros, the mobile dent removal system from Presto is also the cheapest DIY dent removal tool in the test. It is therefore not only a test winner, but also a price-performance winner.

Myth: can dents be removed with suction cups?

Commercial suction cups cannot harm dents – so the myth is not true.

You can often see it on YouTube or in other small Internet videos: dents in doors, fenders or bumpers are completely removed by pulling with a suction cup. When we found a set of suction cups on Amazon that was advertised with the addition “Dent removal tool”, we wanted to try it out and ordered the set for this test. The result was sobering. Neither a large nor a small dent showed any improvement with the suction cups. Even on a dented vehicle door, the sheet metal of which we heated up beforehand with hot water, the suction cups could not improve anything. So, at least when it comes to body parts made of sheet metal, it remains just a myth – and that’s why the suction cups end up in last place.

Conclusion: is the DIY dent removal tool a smart repair alternative?

Of course, none of the DIY bulging tools can replace the work of a professional dent doctor – and none of the tested dent removal sets made the dents disappear completely. Even so, we are amazed at the results possible with a DIY dent removal tool. The dent removal tool from Presto made the dents almost completely disappear with a little rework; The sets by Randalfy and Manelord also delivered a result that was significantly less noticeable than the original dent. Only the suction cups and the dent remover set from Quixx left the dents as they were. We cannot recommend a purchase here. Ultimately, it can be said that the DIY dent remover sets can be an inexpensive alternative to smart repairs for people with the right instinct and enough patience. But perfectionists still have to take the path to becoming professionals.

How AUTO BILD tested it

With a specially designed indenting tool, five large and five small dents were pressed into the sheet metal with the same force.

The first thing to do was look at the operating instructions: How clearly are they written? Are there any warnings? What do you have to pay attention to? Then the scope of delivery and the processing quality of the tool were checked. In order to check whether the dent remover sets actually remove dents, an old bonnet from the scrap had to be used. In the bonnet, we pressed even dents in the sheet metal with a specially designed indenting tool. The dent tool was operated with a torque wrench so that the dents could all be pressed into the sheet metal with the same force. Every DIY dent removal kit had to remove a small and a large dent from the bonnet. The focus was on the individual steps of the application, possible difficulties and risks, as well as possible risk of injury. Finally, the result was assessed.
