The BMW Repair Guide used this 2013 M3 for the following article.

In this article, we will show you a simple form of paintless BMW dent repair that will remove most of your smaller dents and dings.

We write this article with great humility. We have worked on many BMWs over the years here at the Repair Guide, and have made a lot of stupid mistakes (that’s how we learn….right?). But all of our past blunders and miscalculations pale in comparison to what we did to our beloved 2013 M3 one summer day.

After replacing the intake air filter, we did a quick wipe down of the engine compartment with a rag and closed the hood. As the hood came down a wretched sharp metallic sound emanated from the engine compartment; in our haste (lesson #1 learned) we had left a hex wrench set on top of the air filter box. One of the wrenches had dug into the underside of the hood, almost puncturing the metal.

But as Alexander Graham Bell once stated, “when one door closes another door opens”. Thanks Al…it looked like we had just opened the door to dent repair. And although it was a room we were never interested in exploring while writing articles, our bone headed mistake had not only opened the door but had kicked our butts across the threshold.

Paintless dent repair seems to be one of those mysterious unicorns all car owners are trying to find. We want to believe we can remove a dent without sending it to the body shop, but deep down inside we know it will ever work. But with really nothing left to lose at this point, we spent the 35 bucks on an entry level “hot glue” dent repair kit. Our results were actually impressive.

One thing we learned about a hot glue dent repair kit is you will never pull an average dent out on the first try. It is an art-form that requires patience and….patience. It is a slow process that requires pulling on the dent multiple times until it succumbs to your persistence; in fact it took us twelve pulls to get most of the small ding out of of the M3 hood. But the results were acceptable. We were actually able to remove most of the ding with no sign of damage to the paint. We didn’t exactly catch a unicorn…it was more like a small horse with a fake horn glued to its head. But at the end of the day, no one except us will ever know the difference.

Section 1 – BMW dent repair; using the hot glue pulling tool
  1. Plug in the glue gun and insert a glue stick. Allow the gun to heat up at least 15 minutes before using. Make sure the glue stick is inserted all the way.BMW dent repair - install a glue stick in the glue gun and heat it up
  2. Clean the general dent area with denatured alcohol to remove any grease or old wax. This will help the glue tab to adhere to the metal better. Some kits come with a small sprayer bottle which is nice.BMW dent repair - Use denatured alcohol to clean the repair areaWipe the repair area down thoroughly to remove all dirt and wax
  3. The ding on our 2013 M3 is actually inside the hood, so we will be working inside the engine bay. Start by identifying the center of the dent with your finger and marking it with a white colored pencil.BMW dent repair - Identify the dent you want to repairBMW dent repair - Use your fingers to find the center of the dentBMW dent repair - Circle the dent with a white colored pencil
  4. Choose a glue tab that best fits your dent. This is a bit of an art form that you will just have to learn on the job. We started with a slightly larger diameter glue tab and then worked our way down.BMW dent repair - Chose a glue tab that best fits your dent
  5. Liberally apply hot glue to the glue tab, then immediately attach to dent. Apply pressure to the tab for 10 seconds to make sure it adheres correctly. Let stand for 2 to 3 minutes before attaching the dent puller.Liberally apply hot glue to the glue tabBMW dent repair - Press the glue tab onto the dent and allow to harden for a couple of minutes
  6. Attach the dent puller to the glue tab. The dent puller should have an adjustment knob so you can loosen the handle for attachment to the glue tab, then snug it up before pulling.BMW dent repair - Attach the dent puller to the glue tab Use the adjustment knob to adjust the handle tension on the dent puller
  7. Place a towel underneath the dent to prevent a glue tab from falling into the engine when it pops off. BMW dent repair - If working in the engine comportment, lay a towel down to avoid getting glue in the engine
  8. Squeeze the handle of the dent puller with a smooth even action. The glue tab will slightly pull the dent out before popping off the body sheet metal. Remove the residual glue from the paint using denatured alcohol and the plastic glue removal tool included in your kit.BMW dent repair - Squeeze the handle on the dent puller BMW dent repair - Spray the residual glue left on the paint with denatured alcohol Use a plastic scraper to remove the residual glue
