Weld some studs in the right spots and and a few shrinks with the shrinking tip in the deeper damage at the front of the door then work it out now that its tightened up and will stay in place.
Not trying to completely remove this in the steel, beyond my skills, just trying to significantly reduce the depth of the filler. The front was pretty deep and I managed to take the oil can effect out with the shrinks and reduced the depth by a good 80 percent or more. Used Evercoat Rage Extreme for the first time and am really impressed with the way it goes on, virtually no pin holes that I have seen yet, and it sands beautifully with little paper plugging. I'm going to put a light skim over most of the car to try and get it dead straight and this stuff will work nicely and is worth the slightly higher cost.
