Remove Car Dent With Airduster - More amazing video clips are a click away We'd like to be able to explain exactly how this home brew process for removing car dents works, but Physics 101 didn't agree with us in college. The process is simple and involves heating the dent with a hairdryer for 30 seconds to a minute. Next, quickly spray the area with compressed air for about 10 seconds. The last step is to take a step back and listen for the dent to pop itself out. Surely the explanation involves the expansion and contraction of metal due to the hairdryer's heat and the -110 degree Farenheit temperature of the liquid CO2 from the compressed air. The video's producer is quick to point out that his process will not harm your vehicle's paint, though we imagine whatever dented your car in the first place already did.
Thanks for the tip, Dave!
