has anyone tried this? or dose anyone know anything about it? would dry ice ruin your paint?

[jspec240]

damn I gotta try that shit!!! you probably just gave every paintless dent removal garages secret away.. lol

[slow40sx]

yeah, it does work but only on dings, and no it doesn't ruin ur paint, i tried it as a joke when i was getting the sound deadening out of my car and it actually worked

[drfturkey]

dont know if it works but im a try it now....

[seto_s14]

wtfffff no way! gotta try this out

[Xcede]

yep i see not many people knew about this either i found it this morning and was gonna try it but didn't have time to get dry ice today. maybe i'll get some and try tomorrow.

[DreamN]

lol I thought this was common knowledge already in the car community. it does work, but as mentioned only on dings or uncreased dents.

[suprafreak1000]

mhm like said above, i used it on my car and it worked :)

i found out about it a couple months ago from a friend

[steezy]

whoo. i got a sh*t load of dings. i gotta try this.

[miucus]

i wonder if this will work on the huge dents you get wen you roll your fenders

[usajdm]

Wow.......... Im shocked that so few have heard of this.
This is a "super oldschool" trick.

Unfortunately it wont work if the metal has been "creased".

[5t341tH]

wth is it 06 again? whatttt.
jk. this has been out for a while. i tried it with a can of air upside down and it didnt work on my dings

[grnappletree14]

if u use those cold air blowers to clean dust around the pc those work good too. u need to get the cold bottle ones though.

[Matej]

Wish I knew about this before I got carried away with a hammer.

[P_856]

i gotta try this my car has a shitload of dents

[Xcede]

what do you mean by "creased"?

[Inland180]

and who sells dry ice? Where can i get some?

[miucus]

albertsons has some. its locked up in a freezer so ask a worker

[The Chad]

My uncle told me about this. He said he used to use it on his old Vette in the 80's...so i'm assuming this idea has been around even longer than that? It def works.

And a crease is like if you karate chopped a beer can and tried to pop the can back to its normal shape (won't work)....vs if you pushed in on the side with your thumb when drinking it, then realized you dented and and popped it back out. :)

[NismoS13Chuki]

anybody knows how dry iec runs for. i need to get rid of alot of dings

[ZX88]

wow repost... it doesnt work for most dents. niether does the upside down compressed air can. ive tried both the dent has to be big and on a flat area if its creased or on a curve or anything it wont work.

[just1pepsi]

I saw an old school body guy pop a roof on a 55 Chevy back into place w/ dry ice and a torch. Heat the metal then super cool it and boing- it popped into place.. I was warned "not to try that at home"

[HIM]

it works on on small dents, any big dents will fuck up the paint

[Darius]

heh I don't think you want to be exposing your clearcoat to a torch!

The dry ice trick has been around forever. I have yet to try it but a hail storm left 3 dings on my roof so I'm heading to the grocery store to get some dry ice this weekend. It only costs like $1/lb. So cheap.

[mifesto]

it did not work on my civic. then again it has a crease in the dent so it could have made it resistant to simple expansion of temp change

[karl wasabi]

Tried it, doesn't work that great. It does work better if the car is in the sun. Minor dents went away, but nothing big. And sometimes your mind plays tricks on you, cause you want it to work. hahah. So you think it worked, but it really didn't. blah blah blah.

[golfer17]

I got a few hail dings from a recent hail storm, and so I tried this on a very hot day... and it does not work. But I've also heard you need a heat gun to really make it work because you need a quick, big tempurature difference, so I might give it another shot some day.

[SexPanda]

Hiolding a can of air duster upside down is easier...

A little more expensive, but easier.

[KA-T_240]

Doesn't work. I tried getting it hot and then cold. Cold and then hot. I wasted 5+ hours and 20lbs of dry ice.

[!Zar!]

wth is it 06 again? whatttt.
jk. this has been out for a while. i tried it with a can of air upside down and it didnt work on my dings

More like the 80's. Shit, this has been around since before that.

Best thing is heat gun and dry ice.

This isn't for hard dents, only once which are somewhat flexible.

And if the metal has been bent for quite some time, it kind of learns that shape.

The dry ice trick is for new dents.

[Addicted2Kouki]

Explanation:

This only works because a dent is when you stretch metal beyond its shape. By applying the dry ice, you effectively shrink the metal back basically doing the opposite of thermal expansion.

This is why it works better with a heat gun.

Creases don't work because they are "work hardened."




BTW. this has been reposted so many times...I see it every couple of months.
