Testing a trick to see if it can pop out a dent on a tank

Sadly it didn't work.
Your meant to heat up the dent and then rapidly cool it. Done with a hair dryer and a inverted can of compressed air. It is meant to work on car doors and panels.

You did it a bit wrong. You supposed to chill area AROUND the dent, not the dent itself. The point is when the metal is hot it is extended equally over the hot area, but when you cooling it then metal shrinks a bit. So if you chilling all area it shrinks equally and nothing happens. But if you chilling area around the dent then this area shrinks faster then the dent and so dent will be pulled radially. That's how it works. Try again.

This is an obvious point but I'm sure your gas tank was empty, right? If not, the gas would absorb the heat and cold and it would be like trying to sweat fit a copper pipe joint with water in the line. I'm sure you know that but I thought I would mention it for the benefit of anyone who may want to try this technique.

on a tank like that your better off just to put a rag over the tank cap and spray compressed air into the tank and it will pop right out.

Dont get me wrong, but I have a ducati monster down in the garage, and the fuel tank is so thick that I dont think even professionals could remove a dent out of it? Its not like car panel metal :P

@bharatsahni200 Any compressed air. Make sure it hold it upside down. For an alternative use, spray it inside a pad lock and then take a hammer and screw driver and give at her. Result? Universal pad lock opener. Not sure about a door handle though...hm brb. *5 mins later* 49.99 for a lock?!

@dirtysanchezproducti Not true. I hit my pontiac acadian, 1984, rear bumper and a torch and aerosol worked great. Remember, the more heat the more of a chance. And yes, like the above poster said, it's better to spray around the dent and not right in. this keeps the middle, most dented part, more flexible while the cool part contracts and pulls it back into place. Should work on all dents if your creative enough with how you get your energy sources. /know it all off. (I'm 19:P)

@bharatsahni200 Regular compressed air. When holding upside down it sprays out very cold gas.

[dirtysanchezproducti]

it wont work if the dent has a crease in it like this one did.

[bharatsahni200]

what is this spray?

GET A PDR (Paintless Dent Repair) GUY TO GET THAT SUCKER OUT!

that gas tank metal is too thick this method only works well on thin sheet metal.

God forbid you dropped that Ducati in the first place.
