In this episode we're going to test the dry ice dent removal trick. I have been asked about this dent repair method and have always heard about it, but I have not actually ever tied it. That is until, now. Watch the video as we experiment this trick to see if it works for us or not.

I am a collision repair tech. And the dry ice does work when you know what you're doing. I've been in the business 8 years and only saw one pdr tech actually use dry ice. And what he did was use a torch maps gas. Heated the dent starting just outside the crown of the dent. In a circling motion toward the center of the dent and then back out. He moved relatively quick so he didn't burn the paint. Then he slid the dry ice over the top of the dent. Just once didn't hold it there. Didn't let it freeze the paint. And the dents slowly come out. Some dents were deeper than others and took 2 to 3 attempts before they came out.
Does this work on metal fenders also or just fiberglass
dry ice work on fiberglass. fiberglass doesn't dent it breaks
go ahead and hit a panel made of fiberglass and see what it does.
I had just sent my wife to the store for some dry ice and thought I'd check CZcams first. Glad I did, I had time to cancell the dry ice order!
Thanks for the vid!
Thank you for trying this. I am in Arizona and was going to give this a shot on my Tundra. You spared me the test.
You need a heat gun. The point is for the metal to expand and contract extremely quickly. Anyone claiming they got rid of dents using only dry ice must have done so on a hot day.
donnie , i appreciate you trying these so i don't waste my money. thanks.
Thank you for demonstrating this, outside (I'm in SW Florida heat so I thought maybe I could try this with hail damage.) I will seek other methods now, instead of risking frostbite. Did you ever find the best fix? Or does one have to take it to a body shop?
Dry ice is basically useless on 99% of dents.
Unless you think to yourself, "I could easily pop this out if I could reach the back of it", it won't work. Especially on curved sections of metal. The larger diameter the dent and flatter the body panel the dent is on, the more likely it is to work.
The dent is on the hood anyway, you can have access to the backside to pop it out.
just drive an old shitbox with 67 dents in it, nobody will give a shit anyways
The dry ice worked for my daughters BMW. No damage to the paint either!
BuffalosMom Thanks for letting me know. I wish it would have worked on mine.
Stop lying
@@TheTruelakersfan Don't get upset because you don't understand physics.
I think you should try to heat the metal to a certain temperature below scorching the paint and apply dry ice; I have not seen any try or attempt like this!
It is rumored that this method works on only a very small subset of dents. So, might be worth a try. Also, it seems to work better in older cars where the sheet metal is much thicker. Today's panels, if you can take them off, will not even support their own weight, they are almost beer can thin. Cars of the 60-70s are very hard to get a butt print in one if you sit on a hood, saw someone put a head dent in a new car's panel by not doing much. Didn't hurt him but nice round dent in the car.
I was told to put the dry ice in a paper cup then turn the cup upside down on the dent. try to seal it with silicone or something but it's true you should put a hairdryer on it not real close though. just heat then dry ice in cup turn upside down and leave it for awhile
Dry ice dent repair works only if the dent is decently fresh and not age for over a time. Once it age it leaves permanent crease in the metal. Remember heat expand and cold shrink. So on fresh dents heat the around the dent with a heat gun to a point. Where its dose not melt the paint. Quickly rub dry ice around the dent! Not on the dent and it should pop out. I personally never try this on cars but only on aircraft skin at Cessna. I hope this help on your next video.
it's not about the temp. it's about the time it takes to get there. cold or hot. you can shrink panels with only temp. (hot or cold) but like anything. gotta know what your doing.
I wonder if it would work better if you heated a wider area, much as you've been doing but Instead of just rapidly cooling that spot, You might try cooling more area to shrink the metal. there is only so much expansion and contraction to be had in a small area of metal and widening it out might give you more movement. I've seen hail dents go away over time on their own, presumably from temperature change induced metal shrinking and expanding.
Gotta love youtubers. I may try it myself someday :P
I saw a dealer use dry ice on hail dammage and got results. They put a chip in the dent and left it there.
i supect the ambuient temp. may be important.
This and the canned air will work on some, but not all dents.
1. You have to get the dent really hot with a heat gun (a hair dryer will not get it hot enough), being careful to not burn or blister the paint.
2. Then you need to apply the cold, dry ice or inverted canned air spray directly to the center of the dent, not all around it.
What you are doing with the process is heating & expanding the metal slightly with the heat, then quickly cooling the center and shrinking the stretched metal.
I was told that if you heat it up and then cover the dry ice with a sheet of aluminum foil it will work? I don't know if you heated up enough?
Thank you for posting this .. I just saved my money and time cuz this would not work on my dented refrigerator door
It will work. I have actually seen it hail (albeit small hail) and it left dents in my pickup hood and because the rain and hail mix was cold enough when the sun came out and heated up the metal the dents all disappeared.
May I know if it was a black car?
I tried it and it worked for me. I had small dents that the dry ice and hair dryer improved. It didn't totally fix it though, just made the dents small enough that it isn't noticeable. The heat softens the metal and the dry ice makes it shrink.
No it's the other way round
@@rosskstar no its right(other than the "soften" wording), metal expands with heat and contracts with cold, I think youre thinking of water/ice which is the other way around.
use a HEAT GUN.. not a blow dryer.
It does work...I did it on my truck bed side panel. It was a soft dent. We did dry ice. Then gently tapped back with a mallet. Gone and no evidence it was ever there. But hard creased dents. I don't know.
ha ha...gte-r-done! thanks for watching
6:17 like the albino elephant flappin its ears.... :P
Some cars have thinner metal too - big factor.
Dry ice works great , no heat gun!
hi donnie could you pls tell the name of air spray used for removing the dent of the car... I am from India and I want to remove a dent in my duster car
its called a hair drier
The9thGen instagram he might be talking about the compressed air method.
hold and computer keyboard can of compressed air cleaner upside down while spraying. (liquid c02) it will freeze. but hair dryer. use an actual heat gun. (for shrinking electrical heat wrap etc etc)
Rub dry ice for a minute and then dump a bucket of lukewarm water and watch the metal flatten out. Larger the dent, repeat the process by dividing up the dent into sections. This method won't work on ridges formed from a damage.
Thought he kept saying "Hell Dent".
Aren't you supposed to push the dent up after hearing ???
I saw a skip in the vid, makes me wonder why?
A partner get a heat lamp heat to 160* then apply dry ice it ill get done
the two ball bearings on either side of the dent work best
david bradley Thanks for the info.
im from guyana i just tried this on my boss jeep and it worked and i am putting it on my motocycle gas tank and its working so i guess u r wrong in ur vid
I used dry ice on my 1962:ford falcon , hail dents on hood and roof , it work great , its fast , if you hear poping , snaping, cliking noise its working , don't be afraid to put a little pressure on it ( I used a old shirt to hold the dry ice )
Never use never use a acetylene torch on paint you don't want to burn off. Butane, Propane or maps gas. Must be careful can still burn the paint
Thanks, Donnie you saved my lazy ass from dragging out the heat gun and wasting time and money on getting air. Next time use cow magnets as they really worked for getting me 90 MPG on my 350 cu in Chev.ha
Fuk donnie stop lying
Parking the car in the shade before you try it isn't going to work. I did it in Vegas when the temp was 115 out, parked the car in the sun for a couple of hours and then put the ice to it. It works.
May I know what color your car was?
ok so the conclusion is tha it doesnt work....
I remove dents for living via PDR (Paintless Dent Repair). Dry Ice?... ugh. The only time this actually works is under VERY specific circumstances. ie. a very slight, shallow dent in a steel panel. Even then, you have to get the panel quite hot first, then cold really quickly. After that, if you haven't already split the paint, you're still likely to still see a wobble or three. And maybe that's ok for some (ie. racing or beaters). But if you want it out 100%, have a PDR professional do it. There's a real reason why many of us have 100k in tools and decades of ongoing training and experience
☝️☝️☝️A PDR, free advertisement. Heat gun, dry ice, gloves. Get it hot but be careful not to scorch the paint. Then, having the dry ice already ready to go, put the dry ice straight to the dent to be repaired as fast as you can but still protecting the integrity of paint. And before you know it you'll have a dent repaired, a great story to share, and bragging rights over people who try to convince you that you need to pay and outrageous price to get the same or less quality of work.
@@ChadUfferman77 Advertisement? Haha... you're funny :) But seriously, how can anyone just completely ignore dent depth, stretch, complexity, metal type, thickness and paint condition? Simply forcing temperature extremes does NOT magically correct all these variables and restore metal back to OEM spec. Honestly, I wish it did though... I'd be rich.. lol. I've personally fixed hundreds of thousands of dents and I guarantee that, 99.5% of the time, automotive metals will NEVER respond back in the manner you describe. Most "real" dents are inherently challenging, take hard work, effort and years of training to remove 100%. You call PDR outrageous, I call it extremely cost effective (and also a better repair) than a body shop. Seems like you're insinuating that an entire industry is somehow a scam.
+++ Good tries!
What the hell is a hell dint?
It would have worked if u knew what u were doing .. I have fixed mine .. Use. The hot water and push it from underneath mate .. U cant just wet it with dry ice hoping that it would pop out just like it without making any effort . Push the fckn think underneath when it softens up aftr heating it up with a heat gun be carefull tho it may damage the paint if its too close
Magic? Or maybe an extension cord?
Go to a dentist, they specialize in dents and it could even be covered if u have insurance
Auggie Morales haha
heat and cold do not "fix" anything. You should have been doing something while you were heating and cooling. Pull, push the panel for behind. watch some more youtube my friend...
Too much talking..
Spoiler alert: it doesn't work.
just drive the damn car.... nobody gives a shit anyways.....just call it Dimples dry ice does not work... wait to another hail storm,,,,, and call your insurance company stu benjamin
