- Shane Jacks with Dent Pro Upstate, LLC tests another myth about dent removal: extreme heat followed by extreme cold. Will this "pop" a dent out? www.dentsgonenow.com

I do not know if this works or not, but the way you did it will never work. You did not heat the metal with the blow-torch, you just heated the paint and warmed the metal. The torch is too hot. You would need a lower heat for a longer time to heat the metal without burning the paint. It's the METAL you are trying to change, not the paint. Plus I really doubt that was dry ice - I saw no cloud of vapor as it evaporated and you could never have touched dry ice with your fingers.
It was smoking like dry ice.... holding it was super wired though!
The Boy is using regular ice to lol
Start the other way. Freeze it then heat it. I watch s body shop do the roof of my car. It works but you use can of air of some kind blows out extremely cold and a heat gun. The cold goes on top (the painted side) heated goes on metal side (interior) dont know about other panels but I do know it does work on roofs. It looked like a reindeer landed on my roof (hail spots) the same car is a show car. Won a lot of best of show awards. Got painted candy electric blue. Roof was flawless. If I didn't see it for myself I would have never believed it.
If you are reading this: Use a blow dryer on high heat 5-7 inches from the dent for about 2 minutes. You can use an extension chord or inverter or car adapter to power it. Then, immediately following, use compressed air on it. Through Adiabatic Cooling, if you hold the compressed air upside down when spraying, it will get really cold and it will form a layer of liquid ice on the dent. The rapid contraction from this cooling process will probably result in it snapping the metal back to its former glory. Good. If you are working on small dents. If it doesn't work you can try a plunger and hot water but you will probably just make a new dent during the repeated push-in pull-out process.
Oh I should also mention the reason you don't skip the heating process on really hot days, when the metal is hot, is because the heating could be uneven based on several variables and also the blow dryer will give you concentrated Heat at that one location and will be hotter. Using a blowtorch like in the video just results in your paint bubbling up. Not worth the risk
One thing I'm noticing with the ones that do work with this method is if the metal has a dent that has physically changed the shape of the metal it won't work but if the dent is larger and on a seam it will pop out.
Good to hear I have a big ass dent on the seam
Uh, no.
I watched a guy pull out alot of dents but he did it differently. The ice stuck to the medal and when he pulled it off it pulled the dent with it. Also he did it in the hottest part of summer and used really hot, but not boiling water
if it worked he´d lose some costumers...
I removed about 8 dings from my Honda Civic. It does work.
The reason it didn’t work is because you did it wrong and probably didn’t heat it enough. Don’t use a torch use a heat gun and cool it with air duster holding the can upside down.. bump the metal around the dent slightly. Bump it with a closed fist lightly moving around it in a circle as your cooling it. Be careful and use a laser temp gun to monitor your temp so u don’t burn the paint. Dry ice will definitely ruin the paint. 🙄. Done over 50+ dents like this in the last 5 days or so. some can’t be removed if it’s on the crease of the metal or if it overlaps the body line. The dry ice trick only works on the import urethane numbers and you have to Douse it with Water and dry ice make sure it’s super cold. You’re welcome 😎
Agreed as I've seen it work. I Love the air duster vs dry ice as it's easier to keep on hand. What is a good target temp for the heat cycle?
What’s a good heating temperature for the dent ?
I've never seen someone pick up dry ice bare handed. Lol. Get some real dry ice.
Apparently I’ve shown you something new. You should be thankful.
I think that was bullshit trying to grab dry ice I don’t see your handshaking
H ROD I’ve don’t it myself
Could you access the underneath of the panel to address this small dent ?
Yes. Which is how we normally do it, if you will watch some of our other videos. This was just a test to show it doesn't work. I'm sure several will come in and say they've done it, bit none will prove it.
You tried the dry ice trick a week ago and the same cars are in the shop? Your turnover is not so good.
You should probably learn the workings of video and the internet. Believe it or not, you can shoot one, two, heck you can even shoot five videos in one day! Then, post as you wish. Amazing stuff.
Amazingly, no one has proven me wrong yet, despite my numerous requests to do so.
Have a great day! And if you need a dent fixed, call a pro. I’d Imagine if you can’t figure out the inter webs you’re also not very good at other things.
@@TheShanejacks "Well, last week we talked about dry ice, and we tried to fix this same dent." I'm not sure, but your direct quote seems to contradict your point about shooting multiple videos in one day. My point was just observational. Again, not such a good look on your part.
Again, the magic of the internet and filming. Simple question for you: do you think on tv when they say “next week (or last week) on “x”” that they actually recorded it in the time frame being stated or referred to?
Your troll game is week.
@@TheShanejacks I'm a casual observer, not a troll. Your replies certainly show who the real troll is. Why are you engaging my observation? Anyway, the creative professionals in television are successful in creating the illusion of the passage of time. Since your channel offers mediocre opinions, low-quality information, and few solutions, I'll be moving on now.
@@mlcafe my comments are truth, rebutting your comments, which are untrue and speculative.
Not sure how that can be trolling. I have plenty of customers, and I am sought out nationwide to perform pdr. And teach it. So, no, you aren’t gonna get a video teaching you to repair a dent. You can get in line for my training if you’d like. But hurry up, it sells out very quickly.
If you want cheap very cold air or gas put a refill fitting for 1 lb cans in a 20lb propane tank, with a hose with a quick shutoff from Amazon would be ideal, turn upside down and you'll have around -50°f.
What about liquid nitrogen
It should work but it could crack your paint. Weird.
insolatet dry ice?? why????
If you honestly wanted to test high heat then exposure to truly extreme cold you should have sprayed it with liquid nitrogen as it would have chilled the entire surface almost instantly.
Running water over it would be enough
He deliberately fucked thi up
This is the funniest video 😂😂
THAT'S TO SMALL OF A DENT FOR THAT TO WORK! WOW! I'VE DONE IT TO PUSH IN DENTS WITH AN AIR CAN AND HAIR DRYER.... SOOOOOOOOO... NOT BUSTED....
Hey Damian- would love to see your process of pushing in dents with an air can and a hair dryer...
1 of all. Not enough heat. You removed the heat too fast. 2 you are not supposed to use ice but freeze cans that can freeze down to - 43 degrees celcius.
But
Not dry ice. Can’t touch dry ice to skin. Maybe an ice cube is what u had
Heat and water works on large door dents and his dents when done properly. Might want to do more research, there's Even a dozen videos showing it already.
That hood looks aluminum. Heat diminishes quicker.
I think the dents you are trying to get rid of are probably too small, but similar video with larger dent does seem to work ok.

Can you try liquid nitrogen? Dry ice is good. But liquid nitrogen is better.
Needs to be less cold, not extreme, so no. CO2 from a compressed air can is fine.
Hot box works amazing
LN2 would be more effective
Cracks the enamel.
Try using a cold air gun
Man do you even have any technical skills? Blow torch on paint, then That stupid piece of ice... It does work you just have to use the right things: liquid nitrogen and professional "hair dryer"
Praise Be to You Lord Jesus Christ! In Jesus Name i pray! Amen ❤️📖🙏
This is crap. I have great success with this on small dents. Parking lot dings etc. Most of these will completely disappear. I let the dent heat in the sun, then invert a can of compressed air and spray the cold liquid over the dented area, sweeping back and forth a few times. Try it. The cost is a can of compressed air. Dents that involve alot of deformation will not respond. This is not a myth.
Wrong process. Don’t use torch. If you look closely, it did NOT affect the dent… besides, there is no way to get it hot enough with a torch where you won’t also burn the paint. And don’t use dry ice, it is difficult to find and will burn your fingers when you touch it.
Correct process that will work on non-kinked small dents. Use HEAT GUN. Heat affected area in a circular motion for 3 to 5 minutes being careful not to damage paint. Immediately after heat source is removed, spray the dent with MG Chemicals Super Cold spray. This is available through Amazon or locally if you have an electronics store in your area. Also, there are medical freeze sprays used for wart and skin tag removal that will also work but are a bit more expensive.
You definitely did not apply enough heat in the few seconds to have any effect whatsoever. You probably can fix the dent using your method but it will require a repaint of the burnt area.
Shocking! A body shop guy telling people that they can’t fix their own hail damage. What’s next, a taxi cab driver telling people that they can’t drive themselves?
Only an idiot would heat paint with map gas
So much hate on this video.... If you know what to do,where is your video?!
Straw man argument as usual. Small dents like this won’t “pop” back. The metal is too severely deformed and steady. Heat and ice only works for an unsteady, large dent that is “poppable” like those rubber kids toys.
And you’re doing it wrong anyway. Apply heat to the concave side and ice to the convex side instead. Doesn’t need to be dry ice and a torch. A heat gun and water ice works well enough. It works because ice causes the cold side to contract and the hot side to expand.
The heat/ice is only beneficial for hard to reach or dents that require more force than you can manage by hand. And you must have access to the panel from the inside. If it’s on a door panel, the inside decorative crap must be removed, obviously. If it’s on a pillar, good luck.
The dent will never disappear with the heat/ice method. Just gets it less severe so not as much body work is still needed. Only a skilled body repair person can fully remove a dent.
Your comments are hilarious and contradictory. “It will definitely fix on a big unstable dent” then “the dent will never go away completely”. Oh, you mean it will be a small, shallow dent? Like the one I was proving the myth wrong on?
Yeah.
Heat one side, cool the other? You don’t understand thermodynamics and how quickly heat transfers in steel. Hint: the steel is so thin on cars, the transfer is near immediate.
And that only a skilled body technician can fix this. Tells me you don’t know what pdr is.
And on a pillar? Can be fixed no problem. It’s called glue pulling. But you need skill. Which I’ll bet $1000 you don’t possess
Whatever, man. You’ve publicly demonstrated that you don’t know what the hell you’re doing when it comes to using temperature as a tool to remove dents. And if you actively cool sheet steel on one side and actively heat it on the other, one side WILL contract and the other WILL expand, enough to remove a large, unstable dent. It doesn’t matter which metal. Aluminum is even more heat conductive than steel and a sheet of it will do the same thing. This is demonstrated all over the world in every 4th grade science class. If you hadn’t of dropped out in the 3rd grade so your daddy could teach you grunt mechanic work, you might have seen it for yourself.
Yet another strawman argument. I’m not referring to PDR or any other process, I’m only referring using temperature. You look really stupid with your constant strawman arguments. Typical shady af, trash auto body guy
It will not work with this kind of dent in such area, on a flat surface like fender or door it might work depending on the thickness of the metal sheet..
You're gonna F-Up Don't do this
Ok, so everyone saying dry ice works put a cooler full of it in your car and go make $150k a year fixing dents, what are you waiting for……..
Idiot ice it for 20 minutes and shock it with boiling water it works all the time
The comments in here are hilarious.
Having seen your actual work Shane, these are pretty hilarious to read - "do you even have any technical skills?" and "it didn't work because you didn't use a hair dryer" have got to be my favourites 😅
Hello from Melbourne, Aus - looking forward to the next PDR college episode! Hope you and Keith are still planning on continuing with it?
What a joke.. Heating up the spot for something like eight seconds, with a blow torch no less.. 🤦 I guess the objective of this video, is to push people into paying for the professionals to do the job. "Look, it can't be done. You saw it yourself!". I'm not dissing the pros, or their work but at least do an honest test next time.
So many websites give this as advice to remove dents. I don't think any of them have tried it. Only way to get them out is with a dent puller.
The problem with this video is u did not use a hair dryer. That would have worked. I did it once, dent popped out but the wife was not happy coz I almost broke her hair dryer. 1/10 would not do it again.
I would also love to see the suction cup myth. The ones that you buy from harbor freight. Damn customers always asking me about this.
We wanted to show use of extreme heat/cold. And if it does work with a hair dryer but breaks it every time, that's not very cost effective (and we don't have room to store literally millions of hair dryers :)).
..does it really work
I wish I had video taped my dent removal with the Harbor Freight tool. It works quite well, but you'll have to do a few pulls and allow it to cool completely. I proved a body shop and a PDR guy wrong.
Ira Wade He is talking about not using any tools, just dry ice and heat. How don’t you understand that? You don’t need heat, dry ice if you have tools or a glue puller.
"You can try this if you have no tools, but do just so happen to have map gas, a torch, and dry ice on hand."
Question for ya class- do we take any advice from a man who handles "dry ice" with their bare hands?
NO
that's correct class, thumbs down.
Fair enough. Questionable decision at best, but it worked out for me. Tough hands and a stubborn ego.
Your test was bs
