Default Tank dent

Has anyone tried the compressed air & hair dryer dent fixing technique? Just saw it on YouTube today obviously you would drain the tank and take the cap off before trying it

I have on a couple of projects. Make sure you have everything sealed up nicely, and heat the material from the outside of the dent inward.

BTW, works decent on large bowls, sharp dents with crisp lines will require physical body work. Also make sure to inspect the inside to assure there is no damage to the tank lining.

You should be fine, just take it slow.
Talking about the lining in the inside of the tank. For a sharp line, it could have broken as paint would on the outside of the tank. Also, make sure to let it sit at least a few days before putting in fuel, that way if the liner does soften as the paint will, it cannot be cut down with gasoline.

umm, I'm no genius, but I have an idea... compressed gas fumes can cause ignition.. just a thought. I know with flammable liquids in trucks we will not use air pressure to offload it due to this. I don't know how real this is.

a thought... fill the tank with water and freeze it (after sealing tank) the water will expand when frozen. I haven't tried it, but in theory it should work.

Edited: Let the bodywork guys fix it. Any other way and you might ruin the tank. I found these guys that advertise paintless dent repair. http://www.dentsnow.com/ Here is a youtube video of them fixing a bike tank http://www.youtube.com/watch?v=zfRya_ke8Ps <iframe title="YouTube video player" class="youtube-player" type="text/html" width="480" height="390" src="http://www.youtube.com/embed/zfRya_ke8Ps" frameborder="0" allowFullScreen></iframe>

I do bodywork for a living and I've never heard of this technique. Very doubtful it will work. Save your time and consult a PDR or body tech if the dent is that bothering.

Agreed that PDR is the best way to go, but the heat method does work. There is not a lot of pressure required, most of it is in the heating. Matter off fact, if the dent is very shallow you can sometimes pop it out by the heat and cold wet rag approach. But as stated, make sure that the tank is evacuated of all fumes before trying this.
