    Yes, and when it cools the state it returns too is more dense than before heating it. It shrinks. I've done body work for a few years, that's how sheet metal on cars acts.

    I tried this on a dent about the size of a 50 cent peice, it worked to a degree. It made the dent shrink by about 10mm in diameter on the first few tries, but after that it didnt do anything. I then tried it on one half the size of a 5c coin and it did reduce it, but its still there

    Id say it almost works

    @Legen85

    As well, don't you have to hold the compressed air can upside down so it becomes cooler? The guy in the video didn't even do that either.

    wow how is that myth busting when he doesnt know wat hes doing in the first place. you dont spray the center of the dent you want to cool the outside first.

    Flamers!..Geeze! Why is it that everyone has something to say about other's comments? On this subject of dent repair, the main thing to remember is you don't pull a dent out from the middle of the crater..1st in Last out is all you need to know…work the dent out from the outside edges in…THEN use the "Slap and Tickle" .. (Heat and Freeze..) By then most of the stress is off the metal.. 1st in, last out.. Bask in it!

    @aidan21 one problem the spray he was using was colder then liquid carbon dioxide its a car of R13 by the look of it which is -200 deg C i think

    Idiot. Anyone calling themselves mythbusters should start by using the same fucking products used in the videos. It does work idiot, it work best on very specific dents and it has to be applied to the outer edge first.
    1. Get keyboard/computer duster spray
    2. find a dent that looks like it wants to pop back but is bound
    3. heat it very hot first
    4. then spray the duster cleaner upside down to create -180 temps

    It does work because Ive done it. PS stop crashing your car fool.

    it takes about 5 minutes with a hair dryer then spray the can upside down around the outer edge of the dent… he used a heat gun but i am not sure he heated it up enough then he sprayed the can right side up in the middle of the dent… thats why it didnt work

    if it is creased or the dent is a bit old then this trick won't work. However on medium sized dents (also depending on how rigid the particular body panel is) on a larger panels I have tried this and it worked.

    Absolut rubbish. The other videos are using compressed air cans where if you hold the can upside down the liquified gas comes out and rapidly expands causing a cooling effect. This guy is using actual freeze spray which comes out as a liquid if you hold the can upright and rapidly evaporates causing a cooling effect. Those cans dont work upside down and the propellant is not carbon dioxide. Also carbon dioxide is not an ingredient in most spray dusters…

    Reply
  • agoodm

    The sprayduster can I have uses Tetrafluroethane as the propellant, the propellant and ingredients are not listed on my freeze spray. Also trust me; freeze spray is way cheaper than air dusters…

  • darknature79

    same method that we use at the shop with a torch and some water the heat expands the metal and when instantly cooled the metal shrinks and pulls the dent flat.all the people tring it and it doesnt work is cause you have to heat the panel up way over 140degrees

    YOU NEED THE DENT TO BE 'SPRUNG IN' ALMOST LIKE IT IS SPRING LOADED, THIS LOOKED LIKE AN EXTENSIVE AREA OF PUSHED IN METAL THAT DOESN'T HAVE THE SPRINGY TENSION STORED UP IN THE SMALLER DENTS.

    honestly cant say for sure, it's not a can of refrigerant that ya need, it's the co2 propellent that does the job so it is doubful. still tho, worth a try for 2 quid. let me know if it works.

  • MrJenius8477

    This is actual freeze spray. It is designed to be used with the can upright. The type you are referring to is canned air. Freeze spray is used in electronics to keep heat sensitive IC's from overheating while soldering.

    Reply
  • BB75uk

    finally! someone gets it! in the vid they use freeze spray, when they should use canned air upside down for the co2 propelent.
    @MrJenius8477 well said. thanks.

    Reply
  • MrJenius8477

    Canned air doesn't use CO2 as a propellant. It is normally Difluoroethane or the like. The boiling temp of this liquid is -12.5 degrees F. Actual freeze spray uses R-134 refrigerant and can get to -60 degrees F. So they are using the right stuff, the dent just might not be in the right shape for this to work.

  • Riley Carson

    No no no. You still don't get it. The stuff they were using is colder than co2 and is designed to spray out of the can upright. You can visibly see the cold r-134 coming out of the can. That shit is way colder than co2.

    I have repaired car bodies professionally for 20yrs. have used heat to remove or seriously reduce loads of dents.
    the bigger dents work better, e.g if someone kicks your door and leaves a 12" dent. not if someone crashes into your door and dent is an inch deep or more!
    1st gain access to the back of the dent.
    apply heat to the creased area around the dent… NOT the middle! then push the middle of the dent with fist or some wood wrapped in cloth. any square or sharp edges may make it worse.

    Reply
  • Dave Chapman

    if the dent is on a body line (curved) roll a golf ball or something behind the dent while hot…. a hair dryer doesnt get it hot enough but go careful with a heat gun as it can burn paint if left in one place too long! i never needed to use cold air! the heat will shrink the metal slightly and make it easier to push dent out, then natural cooling will expand the metal in its repaired position.
    doesnt always get all creases out but from a 12" monster dent to a barely noticable ripple is great

    considering the ice on the panel after he sprays, I would say that's not compressed air. It doesn't work, I've tried it.

    If anything i would have thought to apply the cold source first, then push the dent out ( i realise the metal won't be as pliable) then as the apply the heat, assuming it should smooth over as it expands, in theory anyway. But either way unless you drive round in an air tight ping pong ball heat change alone won't pop dents out. You'll need pressure from the inside. Temperature change will just be a helping factor.

    that can has a siphon tube where just your regular air duster does not so your getting the liquid tetrafluoroethane not co2 a can like that could not hold the 800+psi that liquid CO2 stores at.

    also it has to be qite warm to work. the thing is you heat it up and rappitly cool(freeze) it and the metal shrinks to its Original size thats the key.

    Heat the middle… cool the edge

    Reply
  • DrRedAxel

    Yea so instead of going through the comments, this does work if done correctly

    1. Don't spray directly on dent, spray on edge to allow metal to "Snap" back to it's natural form

    2. Heat the metal enough to where it is hot to the touch but not to much were paint melts off

    3. Hit around the dent to Persuade the metal to snap back.

    4. Repeat 3-5 times

    I just did this to a used Honda Accord 2000 and a Lincoln Navigator using a Hair dryer and Compressed air (Alternative is Heat Gun and Freeze Spray which does cost more) *Don't use Dry Ice* chance of permanent damage to panel

    I can't answer your question mark because the video was so short. You have to heat for a good while.  You are trying to get to a point where the inside is hot and the outside is cold.  You can't do that unless you hold (they call is soak) the heating process. one minute is a good start. Try it again.
