Dent Repair With Compressed Air? Yes and no....

- Does a hair dryer and a can of compressed air work to remove dents? Yes! As you'll see, it does not work on contoured (bends) parts of the body, but if you have a bowl type dent in a fender or hood; then this fix is for you. $20 and you're on your way.
I didn't bother showing the results of when I tried the areas with the contoured areas because it simply will not work. But a dent 3" or larger on flat surface? It's worth a try. The vehicle in the video is a 2008 Silverado.

Not bad. Im impressed.
The main dent came out. I didn't expect the dents on the crease line to pop out but it looks much better. As for the comment suggesting a heat gun instead of a hair dryer, a heat gun generates enough heat to potentially damage the paint/clear coat finish. Also, if I wanted to use a hammer the fender would have to come off. Much easier this way.
killentime I'm going to try this on a small ding dent. The only thing that worries me is if the dust remover caused any damage to the paint. Did you notice any damage to your paint?
Not a chance. It's just a fluorocarbon propellant for the compressed air. If your ding is truly just a ding, this likely won't work because this is a process of very quick contraction then expansion and it requires a bit of area to work appropriately. BUT; hey, it's not going to hurt anything and I'd certainly give it a try before spending any real money. Good luck.
Sorry so late, didn't see your post. Hope all is well, but no worries on paint unless you use an actual heat gun and get the paint too hot. It would take quite a bit of heat, but that would be the only concern.
I've done the same thing using the hot sun and a few ice cubes. Anything with creases is tough to get out, but I think the results tend to be better if you make the metal colder a little further away from the dent.
One black and one red.

Debgum! Amazing! Danke.
Have you tried the method of cold, then heat, then cold again, then finish with a dent puller?
Well i'll be damned lol......love the accent
This video is the equivalent of watching paint dry.
Amazing.
It didn't work for me but I tried doing it at night rather than daylight, because I was so excited to see if this worked. I'll try it again tomorrow. Should be a nice sunny day in the high 80's. I'll let u know wut happens.
Been waiting 4 years for the update. How did it work out? :)
5 years and no reply what a liar

GOOD VIDEO
Suction cup works just as good and a lot faster
Ok, it came out not perfect but the concept of this it is super, the idea may allow to improve hard jobs.
pretty good
Nice video. PDR ?
Que lastima!!! Porque yo no sé inglés y no entiendo lo que dice, pero bueno con ver lo filmado, Muchas gracias por responder
does it work on metal also ?
Why do you say? I've tried short and long heating methods and neither have worked for me yet. What do you do?
you can get a lot more of it out with a small dent puller suction cup
Where can i get the suction cup nd what is it like
dont listen to these fools commenting .. you did it right and a few more tries it would work & a soft mallot
Forward to 2:40 if you don’t want to waste your time listening to the blow dryer
Or watch all of it for a better idea of entire process and turn volume down.

I would much rather see proof of steps and outcome demonstrated like killentime's way than to see the stop and go videos so many do that prove nothing and honestly complete Bullshit. It is a great video for 3:15 minutes, ty for the tip, but imagine took longer making comment. It's a demonstrative does it work video and awesome one at that. have a blessed day
It doesn't work on small dents like this. And it also depends on the metal -- if it's a composite ( made with a nonmetal) or not. If not, then it won't work.
Estos son los trucos de los almendrucos, pero eficaces, según se puede comprobar.
Why not just place ice cubes on the heated dent... mainly, you're just needing cold to contract the surface?
I know this is super "old", but you have to use the straw tip, without it, you loose temperature and pressure.
Pressure is a non factor. Temp loss between the can and vehicle isn't necessarily true. If it ices up, it's cold enough. Thx for the advice though.
Интересно...на лаке микро трещины появляются от перепада температуры??
Most dents have an easy part that pops out, it's the rest of the dent they don't show you properly most of the time, going all over the place with the camera but besides the right angle and spot to show it as it should be, for example this dent came back where it could have been pushed from behind with a finger or pulling it with a small suction cup and it would have had the same effect so to speak, and then what's left behind, is what most people wouldn't accept to have in their cars for sure, and another thing, when one cooks and cools down the paint in that way, in this case it's a normal hairdryer, and can almost do no harm, but a real HEAT GUN is what should be used and that will be dangerous to use because it can leave dark or lighter patches and even worse, burn the paint if not really careful, and will make it in most cases more difficult for a ''Real Dent Tech'' to not crack the paint, seriously having more chance for micro cracking the paint, because the oils in the paint can only have so much heat and not dry-out to much, especially in older cars with older paint and those that have not been properly after-sprayed, most of these video's are showcases and tryouts for the ones with little to no idea of what they're doing....
To your point of pressing it out from the inside, the entire front fender would have had to be removed, the engine compartment doesn't have holes to reach through. The suction cup method was thought of, tried, discussed with 2 body men I know and no way a dent that deep is coming out with suction alone (possibly with specialized tooling). I could have drilled a hole or two and pulled it out, but I was looking to see how well this worked. Regarding the heat gun, the hair dryer was used specifically to keep from getting the paint too hot and causing damage. Many people have commented on here that a heat gun should be used, but it's not necessary and far too risky in inexperienced hands.
So at the end of the day, for a few $bucks and a little time the fender looked much better. If it hadn't been for the hard contour of the bend the entire dent would have popped out.
No claim of perfection, but given another similar situation I'd try the exact method before spending unnecessarily.
Getting in-between the inner front fender is what we do in most of these cases, if it's not too hard plastic or if it permits us to just loosen up a few clamps or screws, but if needed, we take out the whole inner fender, but anyway I'm not making an argument, some people get into trouble by seeing these king of videos, making things worse for themselves, that's all really, I know some are happy enough if the dent is gone for most part.
Agreed. I'm not selling anything, I just wanted to try it out and it worked better than I expected. For $5 or so you don't have anything to lose if you're going to repair it anyway.
What did you use after the hot air machine ? that spray ?
***** compresed air
***** the kind you use on your keyboard
heat gun will potentially damage the paint finish due to extreme heat. Begin peeling after a while.
Vi proverò e spero di riuscire ..
Buona fortuna, spero che funziona
Hey man, nice technique related this kind of problem, i have a crease dent on my both doors, so how do i fix that n will this technique work or not?
Crease is the key word that makes me believe this type repair won't work in your situation. Instead of some sort of external force pushing or pulling the metal, this is simple expansion/contraction at accelerated speed. The hair dryer heats the metal up which slightly expands the molecular structure, then the liquid freezes and quickly contracts it and brings it back to it's factory stamped shape. The dent can't be too deep nor to sharp an angle. I can't see your vehicle, but if you even think it might work, a can of compressed air doesn't cost that much.
Good luck.
Only works for big dents on flat surfaces not edges or creases.
Because you've got a large dent. You need to do it a number of times, for it to disappear!
awesome does it affect the car paint???
Not if you don't over heat it. That's why the hair dryer vs a heat gun (which some seem to think you need). You shouldn't be able to get it too hot with a hair dryer. If you use a heat gun, you just need to be extra careful, it doesn't take that much heat for this to work.
Muy bien
Well the next time i dry my hair I'm sure to use my air compressor...as i left my hair dryer in the garage.
All comments welcomed. Some simply illuminate the obviously juvenile, pointless expressions of some. It's only worrisome when you think of how many like that vote for the future of our country.
Now that it's on your mind, go put your hair dryer back where it belongs. No idea why your compressor is in your restroom, but believe me, it'll be much easier to do your business once you make that small switch of their respective locations.
A border wall won't help with this.
will that work on a boat
Well it ISN't Compressed Air it is the radical cooling from the propellant and you need to be VERY careful heating some paints ,
The principle is sound BUT does not always work that well , is does however show how a potential repair cost can be reduced greatly or even nullified in some cases.
I suppose I could have titled this "Dent Repair From Propellant Used in Compressed Air Due to it's Radical Cooling Properties", but compressed air just sounded better.

Go straight to 2:40 if you want actually see the results...
what u use right after heat? plz rply
It's canned air, the type used for cleaning computer internals or keyboards. The difference is you turn the can upside down so the propellant (which is a freezing cold fluorocarbon propellant ) is sprayed onto the surface, quickly freezing and contracting the metal, which has just been expanded with the heat. It's a reverse temperature shock which if successful, will quickly constrict the metal and pop everything back to its original state.
Will it work on small dents?
If they are shallow it should. If it's a sharp, deep dent I doubt it, but what the heck? Use your best judgement, but I'm sure you have a hair dryer, if you can spring for the canned air it would be worth a try in my opinion.
un décapeur thermique plutôt mais le meilleurs c'est le marteau a inertie a ventouse
It looks a little bit better and you can actually hear the dent pop when you spray the compressed air. You should try what one person said and use a heat gun not a hair dryer and make a video.
A heat gun would be too 🔥. Will probably damage the paint
Heat it pointing downwards over the crease or from the inside. I wish I was there…
You can't get to the fender from inside without removing it or the inside portion of the engine compartment.
Is it possible on metal? Plzz help me.
Stamped sheet metal as in auto bodies. That's as far as I'll go.
Keep Doing it until all dent is gone
Dents on a crease line won't come out this way. It has worked out a bit more than what shows in the video, but the line where the fender is contoured/creased is too much for this to work. If it was away from the crease I believe dent would be completely gone.
Thx.
I have small dent in nasty crease point above door on roof. Not sure if I should try or pay a pro
It doesn't sound like this would work from your description. But if you're thinking of going to a body shop anyway, if you tried this you'd only be out the cost of the can of compressed air. It wouldn't effect what the body shop had to do one way or the other. Small dents are the hardest, crease lines almost make it impossible.
dent didnt come out all the way bc its on a body line
Yes it does. It doesn't work on creases, and in this case, the crease happens to be on a body line.

i have been looking at all the dent removal videos.Maybe a suction cup and taping the crease would have worked better.
A regular suction cup such as toilet plunger etc. won't work. There are specialized cups you can buy, but the expense is fairly high and this video is only here because I had a dent and wanted to see if this method would work due to minimal cost, and it did enough to show what this approach will and won't do. As far as the taping of crease goes, I don't think anything would change in that a dent on that crease line isn't coming out with this method, nor do I believe a suction cup would do the trick either.
Just look at videos here on youtube.The suction cup is less than ten bucks at Harbor freight.
You're likely correct. I have no idea how many sizes it would take, but I worked oil fields & refinery construction till I retired after GE Energy. 20 years or so of that was in sourcing & purchasing, I wouldn't buy a pencil sharpener from Harbor Freight. No offense.
What spray was it can you tell me and will it get on Amazon
I don't remember, and I don't believe it matters. So long as the propellant is tetrafluoroethane, more specifically I believe it's 1,1,1,2-tetrafluoroethane.
It's a refrigerant and compressed, the tetrafluoroethane is a clear liquid which boils when exposed to the atmosphere and it's extracted from the canned air simply by inverting the can (turning the can upside down) and spraying.

He dented his car just to try this.
using rubber mallet on that dent will be better!
You can use ice cold water instead of compressed air. Metal expands and contracts with change in temperature. Bla Bla Bla you get the point.
if you hold a can of compressed air upside down liquid nitrogen comes out.
Actually it's Co2. Which turns in to a freezing liquid when compressed. They don't use nitrogen because it's flammable.
when you hear that 'pop'
it still looks the same to me
You didn't hold the gair dryer on the deepest paet of the dent,and you should have shakrn up ur can more. If did the whole thing would have disappeared.
If I use a heat gun, which temperature should I set it at? Just wanna make sure so I won't melt my car paint...
+Quan Nguyen Set the temp on high and work the heat into the dent and a couple inches outside the perimeter. Try and heat the surface evenly to a temp that is hot to touch but not HOT, then spray the compressed air with the can upside down. Absolutely do not do as some others have suggested and use a heat gun.... You will ruin the finish on your vehicle.
it'll be more better result if u press it outward from inside..
+richard Acol Agreed; if you opened the hood of a 2008 Silverado and removed the front fender in order to get to it.
Can I use the WD-40 for the compressed air?
NO, no! What makes this work is the propellant (fluorocarbons of some type) in the cans of compressed air that when held upside down to spray, emit freezing liquid which causes the metal to quickly compress after being heated by the hair dryer. The sudden contraction and re-expansion of the metal from hot to cold to ambient is what results in the dent (hopefully) popping out.
WD40 would be totally ineffective.

Bonjour merci du renseignement
I seen time I had a fender dent whent behind it pop it back out than it work than on its own the dent pop back in on its own lmao
Beats me Derpy, but I just noticed this "Isis Nite" post has a "linked comment" statement beside it. Think I'm going to delete it due to the name I didn't pay attention to along with that linked comment statement, which I don't understand. I'm going to leave this here for a while to see if anyone replies to this post with an answer as to what that "linked comment" statement means.
Thx,
this account was made years before isil came out my name is isis not the same thing
Heat gun?
You can use a heat gun if your careful, but it doesn't take that much heat. A heat gun in the wrong hands will ruin the paint around the area being heated if it gets too hot. A hair dryer provides plenty enough heat for the process here.
No. Its special building gun.
Castellano por favor!!!
no puedo hacer eso
I don't get the logic in that one..
Can you repair a dent using iron for clothes ?
No
Use boiling water instead of the hair drier.
Not feasible. You need consistent heat penetration as much as is possible, so the freezing propellant in the canned air will contract the metal back as uniformly as possible.
Hmmmmm....
It probably would’ve worked better if he was able to spray directly on to the dent instead of it spreading everywhere else. He should’ve used the tip that comes with it.
use a heat gun not a hair dryer!
A heat gun would very possibly damage the paint finish. Too much heat. Never use a heat gun for this.
Didn't happen anything 😩
Heat gun not a hair dryer
Still there...
+Ashley Walford The main dent came out. As I and others have stated, this won't work on creases or sharp contours. It didn't all come out for certain, but from an aesthetic point of view you don't notice it in a parking lot like you could before. :~)
The plastic deformation is still there.
There is no plastic involved here. But, yes there are deformities remaining as I've stated. Just use this information as a guide. I'm not proposing this as a "fix all", but it worked to a degree here, and could be all you need given the right circumstances.
all be without the d@mn removed the curse and helps our serenity
will it work for hail dents?
Wow. That's a different one. I'd love to be there and give it a try. Anyway, I suppose it depends on the difference in depth vs diameter (and that's a big 'suppose'). My guess would be if they are shallow dents it may work, if depth is more than width I'd be skeptical. Don't know how many or what size dents you're speaking of, but the larger the diameter and shallower the depth would give me some hope.
What do you have to lose? I'd give it a try. If the first attempt doesn't work, I'd try again right away with a bit more heat.
Good luck, and if you try it let me know how it comes out.
killentime RUclips needs a photo add section lol i gave a small dent about the size of a nickel think this would work

Otra vez será.
Chapista pide llevar...
A hairdryer is the incorrect tool! You are supposed to use a HEAT GUN. Heat guns get MUCH hotter than hairdryers. If you touch a surface after heating it with a heat gun you are very likely to get a 3rd degree burn! As a side note if you use a heat gun exercise EXTREME CAUTION because you do run the risk of melting the paint off of the car!
Doesnt metter wht you use , you just need bring it to right temperature then dropped.
A hairdryer is unlikely going to get the surface hot enough. You're most likely going to mess up your hairdryer trying to heat metal to the proper temperature to make this actually work.
How does a hairdryer get messed up for heating? Stupid
+Paul Hosler But too hot might damage the car paint i guess??
you just saw it work so how is it unlikely

Ha ha ha.. Its still there.. The bit that popped would have popped pushing it with your hand. Pdr is a skilled trade .. Otherwise every idiot would be able to fix dents with a hairdryer..
