Well my welder warped the roof of the Hummer. He made a continuous weld as opposed to multiple tacks (tack several spots, let cool, several more tacks, let cool, etc.). I wasn't there when he welded.

Anyway, whats done is done. Now I've search the forum on how to repair the warp, but found little information. I did find a technique on heating the warp and applying ice to the center. This sounds like a great trick. Has anyone used it? If so, how successful was it. Has it failed on anyone and made the warp worse?

The reason I am asking instead of trying is that I don't want to make it worse. I believe with the current warp, I can pop the warp and tack a piece of metal to the backside as support to hold it from popping back to the warped position. I don't know if welding a support in is a good technique, but it appears like it should work. I don't want to do this if the ice trick is normally successful though.

Any comments?

Thanks,

Scott
