Tips for finding hidden dents on car body
During use, the car body is inevitably scratched or dented.
For large dents, it can be easily observed by 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 to look for and detect and determine the severity of small dents.
- Use your fingers to feel the suspected dents in the areas you are having trouble with and this is the easiest way.
- Observe the reflection of straight 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 to 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 an area 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 crayon, use a dry ice cube that fits the size of the dent to apply it in the right place. Then, use a cotton towel to wrap the dry ice and apply it continuously to the dent for 10 to 20 minutes; remove the towel and observe by looking at it from the side. If the dent is still faint, continue applying it, then use a clean towel to wipe it again.
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 can upside down and spray on the heated area, turning it upside down will let the coldest air in the can 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, making 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 highest vacuum mode. This also helps to quickly remove 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.
