Tips for finding hidden dents on car body

For large dents, it can be easily observed when looking at the car body. But for small dents, especially on dark painted car bodies, it is very difficult to detect.

However, there are some tips for looking and detecting and determining the severity of small dents.

- Use your fingers to feel the dents in the suspected areas and this is the easiest way.

- Observe the reflection of straight-line objects on the car body to quickly determine the location of dents. If the car body is not dented, the reflection of objects on the car body is normal. If the car body is dented, the reflection will be distorted or deformed.

How to fix dents on cars

Use boiling water

This is a fairly simple way to deal with dents. However, it can only be applied on parts made of plastic.

Accordingly, pour boiling water on the dented plastic part to expand the plastic, then put your hand behind the bumper and push the dented part out.

If the dent is in a position that cannot be reached from the inside, after pouring out the boiling water, immediately pour ice cold water over the dent. The sudden change in temperature will return the dent to normal.

Remove dents with dry ice

Dry ice (also known as smoke ice) is solid carbon dioxide used in preserving food, medical pharmaceuticals...

First, mark the dent with a wax pen, use dry ice that is the right size to apply it to the right spot. Then wrap the dry ice in a towel and apply it continuously to the dent for 10 to 20 minutes; remove the towel and observe by looking sideways. If the dent is still faint, continue applying more, then wipe it off with a clean towel.

Use a hair dryer and compressed air

First, turn on the hair dryer on the highest setting and heat the dented area for about 2-3 minutes. Immediately after that, turn the bottle upside down and spray on the heated area, turning the bottle upside down will let the coldest air in the bottle escape. When the hot air meets the cold air, the plastic part will pop out, returning to its original shape.

Using a vacuum cleaner and funnel

Use tape to connect the vacuum cleaner head to the funnel to make sure it is completely sealed. Then tape the funnel so that it covers the dent in the car.

After the gluing process is complete, turn on the vacuum cleaner at the strongest vacuum mode. This method also helps to quickly handle the dent on the car body.

Use a stiff metal rod with the tip curved up.

If the dent is in a place where you can insert a metal rod, use the curved end of the metal rod to apply pressure and the dent will disappear.
