- Gaarra, on 10/11/2007, -3/+37English is probably not their first language?? I know it's hard to believe!
- sancho320, on 10/11/2007, -2/+18I just went and put a dent in my car to try it out... It didn't work. Any other ideas?
- krazytom, on 10/11/2007, -0/+13Gaining points?! HHR fully loaded is under 20K, and IMO is an ugly piece of *****.
- bysin, on 10/11/2007, -0/+11Inaccurate. Compressed air does not contain carbon dioxide. It contains difluoroethane.
- tw0bit, on 10/11/2007, -13/+23Did a two year old write the captions? "wait until ice disappear" "this technique cause any dommage to the paint"
So does it cause 'dommage' or doesn't it? it wasn't clear - digidelia, on 10/11/2007, -1/+10i would imagine this only works on large shallow dents, not on coin-sized dings and whatnot
- R2Bacca, on 10/11/2007, -5/+14I think it was probably either translated or written by someone who doesn't speak/write fluently in English...
Try thinking about it first... Or are YOU the two-year-old? (you forgot the hyphens in the phrase "two-year-old"... since we are nit-picking....) - gamer31, on 10/11/2007, -2/+10I went out and bought some dry-ice today to try removing dents from my car, but it didn't really work. I'll have to give this a try, it looks like it would be a lot easier and probably cheaper to do.
- garrettnb, on 10/11/2007, -2/+10notice how he must mention the name of the car? Almost as if he is trying to gain internet points by saying: i have an expensive car.
- BESTenemy, on 10/11/2007, -1/+9 It makes big of difference what the shape of the surface was prior to getting dented. By heating up metal you are generating a hot spot. Then you freeze the center of it, you're forming a doughnut with edges that are still hot, pulling outward, but the cold center trying to contract. It's like pulling a piece of fabric over a frying pan.
Both, the edges are trying to deform themselves to match the curvature of the dent and the dent is trying to deform to match the shape outside of it. If your dent happens to be on a flat side of the car, then you're pretty much stuck with conventional methods - block of wood and a hammer, suction cup or some non-permanent adhesive.
You've got nothing to loose by trying the method in the video. Keep in mind that very basic physics is involved. The higher temperature contrast you can achieve between the cold spot and the edges around it, the more likely you are to succeed, provided the dent is in the right place (on a curved side). After heating up the metal with the fan and applying liquid gas, you can use the fan again around the cold spot to increase temeprature contrast.
The video says paint does not get damaged in the process, but it does. Paint expands and contracts at different rates, so if the paint job's cheap, don't be surprised if you end up worse than before you started. - clide, on 10/11/2007, -1/+8It isn't CO2. Strange that the guy looked up the temperature of liquid CO2 at 1 atm, but didn't didn't look up what was actually in the can.
http://en.wikipedia.org/wiki/Gas_duster - shawn5300, on 10/11/2007, -0/+5Tried this on my Ford Taurus, didn't remove the dent or anything. I heard it only works on some cars and it depends where the dent is located.
- ryanvsrobots, on 10/11/2007, -0/+3they don't use this method traditionally because they can just use a large suction cup like device, which is cheaper and faster. my friend is a used car salesman and uses it to get dings out; he used it on my car once and it worked also.
- razmig, on 10/11/2007, -0/+3what? I live in America and every can of air that I know of does that when sprayed upside down, sort of burns the skin too, found that out the hard way.
- yow1, on 10/11/2007, -0/+3could anyone actually see the original dent?
- JohnKappa, on 10/25/2008, -2/+5It's one thing to remove the dent, but another to get the moose out...
http://www.zenwaiter.com/moose/Moose2.JPG - STARTSOMETHING, on 10/11/2007, -0/+3The hhr lasted what 2 years Chevy finally stopped making them after probably loosing millions
- zodieman, on 10/11/2007, -0/+3About the English thing: Look at the picture of the car. Snow + poor English = Quebecer. He's not Asian, sorry folks.
- RyGiL, on 10/11/2007, -0/+2"Snow + poor English = Quebecer"
Interesting formula... but what do you add to the equation to result in a Russian, German, or pretty much anyone from a region that gets snow where English is not the native language? - anti_hax0r, on 10/11/2007, -1/+3That was your car? Sorry, I couldn't help myself.
- Gaarra, on 10/11/2007, -1/+3Very interesting. I'll have to try this out!
- Wireddd, on 10/11/2007, -0/+2nope those are the same cans that we have in the US
- Jo9100, on 10/11/2007, -0/+11. look at word 'dommage'
2. look at user 'loup226'
3. remember the beer scam video from him, there were quebec flags somewhere - elusive, on 10/11/2007, -0/+1On most newer cars you should be able to remove a dent just using a hairdryer. They use plastic that regains its original shape when heated. I'm not sure which manufacturers use it, but I have fixed a couple dents on a new Nissan Altima with this method.
- dawglse, on 10/11/2007, -1/+2Since when was a HHR expensive? pffft
- colonelpanic, on 10/11/2007, -1/+2Gonna cop can of air form work tomorrow and give this a try on the parking lot door dings I have. I've heard about The dry ice trick before, but I could see this working-though it seems the metal they popped the dent in was quite thin. One would also have to wonder why this isn't used for traditional paintless dent removal (probably because it doesn't work, or at least not well).
- HotMovies, on 10/11/2007, -0/+1I dented my hot water heater while putting away some Christmas decorations... Think this might work?
- lolSTG, on 10/11/2007, -0/+1Reed Richards: Time for your lesson- Chem 101. What happens when you rapidly cool hot metal?
At least Doctor Doom won't have any dents in the sequel! - Doghound, on 10/11/2007, -1/+2@tw0bit
I agree with you on the whole English language thing... but give the guy a break; as gaarra said, it's probably not (I say definately not) his first language. He could be trying out his English english skills rather than using a translator of any sort.
Anyway, I answer you question of "does it cause damage to the paint or not" with this: it's possible it could. Liquid CO2 is very, very cold, which paint coatings typically do not like; yes, they can withstand a very cold temperature, but negative 100+ is not what they are designed for. Add that to the shock factor of going from +100 F (guessing from the hair dryer) to -(whatevert) F is probably not very good.
Nothing likes being shocked freezed.
Although, science can be a very strange thing sometimes. So, I can't positively answer your question. - taiwanniggadu, on 02/11/2009, -1/+1nice little trick. makes me want to dent my own car just to try it.
http://www.rentalcarscode.com/ - joshtheitguy, on 10/11/2007, -0/+0this one won't work for me Mazda uses metal on the doors where my dent is
- MrsButtersworth, on 10/11/2007, -2/+2Is it necessary to indicate in the title that the link is to a video, when it's already in the video section of digg?
- Al3x, on 10/11/2007, -1/+1mrsbuttersworth said this at the bottom, but it probably won't get seen...I lol'd
"Is it necessary to indicate in the title that the link is to a video, when it's already in the video section of digg?" - frenchdiggler, on 10/11/2007, -5/+4English Motherfu*$er, do you speak it?
- natey3, on 10/11/2007, -3/+1He just wants to let the internets all know he's about to go ruin the paint job of a car worth more than most diggers salary for 2 years. Congrats
- garopedo, on 10/11/2007, -3/+0Pretty much what this does is expand and shrink the metal behind the paint... It will work on most small dents. The downfall is though that if you hold the dry-ice or the heat to it, it'll either expand or shrink to fast and you'll end up with more of a disfigured looking car rather just a dent.
- SilentKnight121, on 10/11/2007, -6/+1First of all, i don't think here in the US that we can get cans of CO2 like that, our office/electronics dusters are a different chemical, but probably just as effective.
- rickremixx, on 10/11/2007, -6/+1i think i am going to try this on my chevy HHR that got a dent from a shopping cart on the fender
- garopedo, on 10/11/2007, -11/+0Offices dusters use Liquid Nitrogen. You can buy dry ice in stores.
