Has anyone used that special tool that folds the end of the panel in (both sides) creating a "V" you then weld in the "V" area, and there is less grinding to do afterwards. seemed like a good idea because the grinding creates more unneeded heat, and also the fold would make the panel stronger (?) and maybe cut down the warping?? but i would only use that if you could not see the "V" from inside (such as a trunk area.)
