After several attempts I finnaly gave up. I thought it was going to work.

Sat there, held the blow dryer until the metal was hot enough to where i could push it with my finger and it would move a little, grabbed the air can, and blasted it.

But since it was pissing me off enough, i removed the ecu, and i could fit my hand inside the frame so where i could somewhat push it and it worked a little. The dents still kinda there, but not as a circle, definently less noticeable.

 

LMAO!

I have seen that little trick on youtube but have never bothered to try...

A heat gun maybe
I think the way you went about it in the end is your best bet for a quick fix

 

i thought you got it cold and then put the heat on it. either way i tried it on a old car of mine and it did not work for me either.

 

Nope the idea is to loosen it up with the heat a little and snap it back to the memory of it's formed shape by quickly removing the heat with compressed air. Didn't work on my quarter panel either, and since they're double paneled and I have an onstar computer whose bracket is directly behind the dent, I had to use a slide hammer and then repair the small hole and the paint

 

i've heard of this before, but always wrote it off to an old wives tale.





now i know why.

 

I've always heard to use dry ice, but I've never seen it done or know anyone who's done it. Quick! Call Jamie and Adam at Mythbusters!

 

compressed air wouldn't be cold enough i suspect rly - unless ur compressor is pulling air from say a sub freezing temperature outside & u have the tank somewhere away from the heat as well. CO2 maybe would work better?

 

I have seen this "trick" done a few times at a local body shop with success. They used a heat gun and a product made by Roly called Spray Freeze. It's intended purpose is to freeze electronic components for testing purposes. The key to it is the type of dent you're trying to remove. If the metal on the circumference of the dent is creased it will not pop out. Compressed air will not get the metal cold enough to react. Some use the CO2 from (upside down) aresol cans, but the Spray Freeze will get the metal much colder and reaction time is reduced.

 

Compressed air, when turned upside down it shoots out some freezing material all over the place.

 

this is true ^^^ u send out uncompressed liquid oxygen (stupid cold too) when they're upside down or hell if u shake them they do it too.
