Fix Dents Using Compressed Air and Hair Dryer - Does That Really Work?

[samueltheboss1]

Hey, your the only person who is actually honest, though can I ask you, what video editor do you use?

[DonnieSmith7]

@samueltheboss1 Thanks for watching. I use Macs iMovie to edit this video. However, I had the intro video part of the video made for by someone else.

[nameshamebaddrivers]

Perhaps if you had not have let it cool down so long before you applied the air... works here when red hot... not luke warm..

theres a guy in the car pushing the dent out

[dimebagcfh]

be very careful turning the canned air upside down unless you wont frost bite it does contain something inside of it sorta like they did on terminator 2 where they froze the guy with liquid nitrogen. also i've always been curious would a household plunger work to get out dents?

[DrDance2323]

If you heat the center of the dent and spray the center of the dent, not much will happen, you want the OUTSIDE metal to pull on the dent making it flatten out. Think about it like hammer and dolly, you wouldn't just bash the deepest part of the dent, you'd slowly get the metal to pull the dent out, I repaired an ex police car like this that had all sorts of minor dents in it. Only used hairdryer and compressed air can, and even after a high polish no dent is visible at eye level.

[DrDance2323]

Absolutely this works as long as the metal is not creased. I have repaired all sorts of damage using this method. First heat from the outside in not from the center out. the hottest spot you want it the rim of the dent, not the dent itself. Spray the rim of the dent not the dent. The cold contracts, pulls the creases out, it doesn't pop the dent as you were expecting. You sprayed the dent but it's the surrounding metal that pulls the dent. I start heating about a foot from the dent and work in.

[DonnieSmith7]

@DrDance2323 Thanks for the detailed instructions. When I get a chance, I will give it another try. Thanks for watching.

You have to use a heat gun.... Hair dryer is not hot enough

[stavrosdra]

Bla bla bla.. makes no result.He may did it on purpose.It works guys!!

[jacoley]

maybe if you had everything ready to go, i just about bet you lost half your heat. This is a modified technique used in the body industry for years. Using a torch and wet rag. Not trying to rain on your parade it would help if you understood the process and followed through it before making a statement about what works and doesn't..

[DonnieSmith7]

@jacoley I have used the torch technique many times on older cars for hail damage. However, you do not use a wet rag for that method. The heat alone will raise the dent. The heat and wet rag method is used for shrinking (oil can) stretched metal not dent repair. I tried 3 different dents in this video and I did immediately freeze the last two and still no luck. Besides I want to do this form the perspective of the average who is trying to fix their own dents.

[Jossy92]

@jacoley Worked great for me by doing it correctly. Cold first until the dent and surrounding areas are frosted: metal contracts. As the metal warms naturally the expanding metal will pop the dent out. The smaller and more concentrated the dent, the more likely it wll work. 

[born2burn1]

that must be good for the paint job

[4G63PWR]

@born2burn1 Carbon dioxide, oh the terrors. Tap water is worse.

[born2burn1]

@4G63PWR I was talking about heating and rapidly cooling the material. It really doesn't metter with what. No harm done to the metal as at is elastic to some extent, but paint is much more fragile.

[ericngohp]

lol look at this fat ass cracker

[DonnieSmith7]

@ericngohp But I have been drinking slim fast....lol

[rayfire50]

you wait too long

[DonnieSmith7]

@rayfire50 I tried 3 times. The last two I spray immediately after heating.

[defrag220]

waited to long ..

[AFXMonster]

your waiting to long in between heat an cold it has to be right after so it freezes

[DonnieSmith7]

@AFXMonster The last two I spray immediately after heating.

[TerraDigitalMedia]

I've done this and it absolutely works.. what this guy and a Lot of other people do is they don't put enough cold air on it.. you can't heat it for 1 minute or 2 and then hit 4 seconds of cold.. you gotta really freeze that up... it does work and its way better on big "soft dents' obviously any paint broken or "edges" in the dent you're likely going to still see some damage... but if you've got a big depressions that doesn't have any breaks... this works period!

[DonnieSmith7]

@TerraDigitalMedia I will give it another try when I get a chance. Do you use the entire can on one dent?

[smitty71XX]

You can search "Brule's Rules" on YT for other useful tips!!!

[smitty71XX]

You'd be surprised what a basketball or football (deflated) when placed in behind dent..(I've done it on doors and rear quarters MYSELF and it works.) inside door panels off, windows UP (or,...trunk liner removed).. rig spacers for suppor from opposite wall/door via (scrap 4x4's or whatever) ....then inflate (THINK ABOUT IT) not makin a vid..sorry. Dent, ball, SUPPORT. POP!!!! Gasp!!! F that hair dryer crap...THIS WORKS! You turkey! "For your health" --Dr. Steve Brule

[DonnieSmith7]

@smitty71XX Thanks for the tips, I will have to give the ball trick a try.

[Choad01]

Nice video. You might have had a better results getting the compressed air on the dent right as you took the heat off. In metallurgy class I saw metal snap using a torch & dry ice. I have some dents in my jeep hood that I'm going to try a heat gun and air/wet rag on. If I get good results I'll drop a line back. i have your channel subscribed.

[DonnieSmith7]

@Choad01 Thanks for watching.  I'll give it a try.

[1dEEPLincoln214]

Funny thing you say something about Snap on, because my two older brother that work in an Auto Shop (Painting Cars and Repairing Crashed cars) they buy stuff from Snap On and your right they do go about every week to sell their product.

[JohnCarey1963Jag]

Donnie, This is a cool idea. I'll let you know if I come up wtih anything to test.

[DonnieSmith7]

@JohnCarey1963Jag Thanks, I would appreciate it!

[DonnieSmith7]

What products would you like to see tested? 

[karattini]

I serch for this and I notice that for people that this work is on large dents that will come out easy by hand anyway but had no hard nerve to ir like when someone lean an a door get dented gently.

[Formula400Pontiac]

@karattini Probably right. This working would demand a miracle of some kind. lol... And as we grownups know, miracles really don't exist.

Think about it. If this was correct (with the hair blower) peoples cars would be deformed just by hosing it down with cold water after they were left standing out in a baking sun for some hours.

[DonnieSmith7]

@Formula400Pontiac This was the first time I actually tried this method. However, I have never seen hair dryers hanging and a shelf full of compressed air at any of the body shops I been to or worked at. I thought I would give it a try myself to see.

[Formula400Pontiac]

@DonnieSmith7 Yeah that one is good. Testing it with an open mind is all good even if it sounds somewhat far fetched. I'm a skeptic ( rational thinking, demanding good solid evidence, supporter of good science and all that) and you sir did do a fairly solid test on "that claim".

Good one! Hope you test more.

[karattini]

This is a good section. will you tested with a Heat gun?

[DonnieSmith7]

@karattini sure, I can test this using a heat gun. That may make a difference.

[karattini]

@DonnieSmith7 you can also try to use dry Ice I saw a video with dry Ice or try shooting longer time with the spray can an also try to shoot the spray faster maybe the trick is in the rapid change of temp and if you whait long it may be colder.
