Taking care of your vehicle is important for prolonging its lifespan and keeping it working at its best. But sometimes accidents, breakdowns, and damage can occur be it from human error or simply because a part has come to the end of its lifespan.

A dent on your car is one of those issues where it might not seem like a big deal at first but it can actually become a nuisance if left unattended for a long time.

Dents can occur from accidents, the car wash, by a car door from a vehicle parked close to you, and even shopping carts too. Hail damage can also result in car dents which can seem unfixable when you are doing this repair on your own.

But fixing car dents is a DIY task that anyone can perform without having any additional skills.

How to Fix A Car Dent


When you’ve located all the dents on your vehicle go ahead and measure them. This method works on shallow dents that aren’t located along the edges and with a diameter of at least 3 inches (7.6 cm).

The materials and items needed for this car dent repair method are going to be the following: a full or nearly full can of compressed air, heavy-duty insulated rubber-coated gloves, dry ice, hairdryer, and aluminum foil.

  • Start by applying heat over and around the dented area for 1 to 2 minutes. Have the hairdryer set at medium level and make sure you are holding it about 5 to 7 inches (12 to 18 cm) away from the surface. Avoid overheating the dented area as this will damage the paint. Once 1 to 2 minutes of hot air being blown on and around the dented area have passed take a piece of aluminum foil and place it over the dent.

  • This is where you can choose to do this car dent repair method with either dry ice or liquefied compressed air. The sheet of aluminum foil will keep the area warm and also protect the paint from getting damaged from the dry ice. Make sure you have your heavy-duty gloves on to protect you from frostbite and start applying the dry ice/ compressed air. For those of you that are going to be using dry ice, rub a block of it over the aluminum foil with one hand. For people using compressed air, just turn the can upside down and spray over the dent so you cover it with liquid ice.
  • No matter which solution you use, dry or liquid ice, you’ll only need to apply it for about 30 – 50 seconds. This is because the panels of today’s vehicles are made of thin and light material which will cool down quickly. When you’ve applied either solution you will hear a popping sound which means that the dented surface has popped back into place. The quick shift in temperature makes the material get back into its original position. You’ll need to wait for a while until you hear the popping sound – this depends on how thin the panel is. Remove the aluminum foil and dispose of it properly once the dent has been fixed. If you used liquid ice/ compressed air you’ll need to wait until the foam clears out from the surface and then wipe away what’s left from it with a gentle cloth.
  • Some dents won’t be as easy to remove as others which is why you’ll need to repeat the whole process multiple times. If you happen to see some improvement but the dent isn’t fully removed do the whole thing again but avoid overdoing it. Whilst the heat from the hairdryer can help you manipulate the exterior, the extreme cold from the dry/ liquid ice can cause damage to the paint.

Why You Need to Repair Dents


Every car fix no matter of what scale it is, safety is going to be the most important reason for why it’s done. This goes for dents too especially when it comes to dents caused by front and rear bumper collisions.

These accidents can lead to dents that can compromise the safety of your vehicle which can be the cause of a much bigger issue.

Rust & Paint Damage

Paint damage can occur from a dent too which can not only be visually unappealing but it will also get worse and worse the longer you leave it sitting there.

This can lead to the paint flaking and peeling off. An even bigger concern here is the formation of rust. This may not be immediately visible but over time it can grow into a bigger issue. Rust forms since the dent has layers underneath the paint exposed to the elements.

Resale Value

Since the outer body of your car will be damaged this will also affect its resale value. When leaving dents unattended for a long time even if you were to repair them after that period has passed the spot where the dent was won’t be the same.

This affects the state of the car and it shows how well it’s been looked after. Fixing your dents will increase the resale value even if a car is old and in an overall poor condition.



Sometimes even a little mistake can lead to this problem, not always you will be the guilty one. Don’t worry at all, this is something that can be handled very easily if done correctly.

Fixing a dent on your car in many cases is a solution that 99% of drivers can do. Give this method a try, and let us know if it works for you!
