Fixing small dents - a secret that garage owners would not like you to know

kalaks2000 · 2nd May 2009, 18:21

Hi Folks,

Has anyone tried this method of removing dent with dry ice in Bangalore. I tried to locate some dealers and they don't have the dry ice here..need to look at far of places at Malleswaram and localities. I stay on airport road...any suggestions..

Right, so I had a look at this thread a few days back (I have a few dents which arent worth the MASS estimate given to fix them). The theory seemed to be sound- that metal will contract when cooled rapidly.
So I went to the local ice cream guy (one of those cycle cart guys) and asked him about dry ice. He explained that they get it from the supplier factory in Badarpur (I live in Delhi) for free of cost. So I asked him if he could get me some- as luck would have it, he had some with him right then and was happy to gove me some.
So I came home and tried the dry ice rubbing bit. I have three dents- one is a scratch dent- from a cycle that fell on the car, one is a slight depression where a bike barely bumped me and a third is a large scraping deformity made by a ^&%^$@! drunk driver.

I tried on all three dents. Unfortunately, it didnt work. I remained at each for atleast 10 mins- tried rubbing gently, tried a bit of pressure too (melting point decreases with pressure)- nothing happened. The dents are still there, happy as ever.

Hmm, so this is another myth. Silly question, but it was dry ice that turned directly to vapour? And the way it is supposed to work is to just hold it in direct contact with the dented metal to supercool it for it to jump back into place, using a piece of cloth to keep your hand intact.
Has anyone else gotten this to work?

@ sawyer- that's right, CO2 cant exist in the liquid form at normal atmospheric pressure. Which is why it sublimates directly from solid to vapour (much like napthalene balls).

I guess it is a myth. Unless if I'm doing it wrong?

Has anyone of ever used Dent King or is aware of it? This product is from Wonder Brands and being advertised a lot on Tele-shopping channels. Here's the link to this product on wonderbrands website:

This product reportedly removes any small/medium sized dent (they call it pop-a-dent). I am actually thinking of purchasing it; however, the general reviews on internet about this product are not very encouraging.

Any light thrown on this matter would be highly appreciated.

Brother had tried it, and apparently was a wasted effort. He threw it into the trash after that.

Thanks for this really quick response mate; Looked to me a total waste at the first glance; however, somehow got tempted to try my hands on it and hence this thread.

Might as well give this a try

I have many times seen the advertisement on television and was tempted into buying one.

Condor: Did it work atleast in removing part of the dent or was it just like a cheap chinese toy?

condor · 25th May 2010, 13:15

@MAS, apparently not good atall.

Incidentally, I was checking out such stuff. This particular one uses glue and I was skeptical about it till my brother confirmed it's 'value'. This thing is also priced well above it's cost on Amazon.com.

Suggest you guys try the one that @BBlost has provided a link to. It's cheaper, and in case it doesnt work, then you can still use it at home for what is actually intended for

From what I found in TBHP, this product is not much appreciated. Here're few other links on removing dents, if that is what you're looking at

When I was a student in the UK in the 70's garages would often make a tiny hole and then use a jig which was essentially a heavy block on a bar with a small screw at the end to pull out the dent - was called the dent puller. Once the dent was pulled the hole was covered up with epoxy, and the paint touched up or a decal put. Now you can use a hot melt glue in place of the hole. That is all.
