Dent Repair Time – Varies
Nothing is more irritating than a small dent or ding on your BMW. In this article, we will show you a simple form of dent repair that will remove most of your smaller dents and dings.
I write this article with great humility. I have worked on many BMWs over the years, and have made a lot of stupid mistakes (that’s how we learn….right?). But all of my past blunders and miscalculations pale in comparison to what I did to my 2013 M3 this past summer.
After replacing the intake air filter, I did a quick wipe down of the engine compartment with a rag and closed the hood. As the hood came down I heard a wretched sharp metallic sound; in my haste I had left a hex wrench set in the engine compartment on top of the air filter box. One of the wrenches had dug into the underside of the hood, almost puncturing the metal. I was sick to my stomach.
But as Alexander Graham Bell once stated, “when one door closes another door opens”. Thanks Al…it looked like I had just opened the door to dent repair. And although it was a room I was never interested in exploring, my bone headed mistake had not only opened the door but had kicked my ass across the threshold.
Dent repair had always interested me….and I had often wondered if any of those paintless dent repair kits actually worked. I was skeptical to say the least. But with really nothing to lose at this point, I spent the 80 bucks and got an entry level “hot glue” dent repair kit. My results were astonishing.
One thing I learned about a hot glue dent repair kit is you will never pull an average dent out on the first try. It is an artform 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 me twelve pulls to get the small ding out of my hood described above. But the results were amazing. I was actually able to remove the ding with no sign of damage to the paint. I won.
No parts are needed in this repair
Tools and Supplies
Paintless dent removal kit
- 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.
- Clean the general dent area with denatured alcohol to remove any grease or old wax. This will help the to adhere to the metal better. My kit came with a small sprayer bottle which is nice.
- 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.
- 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. I started with a slightly larger diameter glue tab and then worked my way down.
- 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 .
- 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.
- Place a towel underneath the dent to prevent a glue tab from falling into the engine when it pops off.
- 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.
- Repeat until dent is satisfactorily removed.
As previously discussed at the beginning of this article, it took us twelve tries to complete the dent repair. Deeper or more sever dings may take longer. Just use patience and persistence, and you will be successful.

The Repair Difficulty Level displays graphically how challenging the repair is, from easy to advanced. Easy repairs usually require very few tools, have short repair times and do not require jacking and supporting the vehicle. As the difficulty level rises, expect the repair to demand more time, specialized tools, and better understanding of mechanics to complete the job.
