So when inspecting my car for winter a week ago I went over the undercoat everywhere to make sure it was OK/no bubbling....I found about 5 places where it seemed rust may be underneath, and I peeled off the undercoat to find HORROR in 3 of the 5 locations, two of them were surface rust and have been treated. The others are a bit more scary. I am working at grinding and cleaning off these areas, but what I want to know is, after looking at these pics, do you think I should go ahead and have the two major holes welded? Or just grind the rust off, treat them super well with rust preventer/converter, and then seal them up with undercoat material....? My dad's friend can weld these area's shut tomorrow once I have finished prepping the surrounding metal, but I would like to get views from here on the forum about what would be the best solutions to this.

By the way, the real dark black looking shiny stuff on a lot of it is the rust treatment stuff, its pretty amazing.

Pictures are below:





You can see in the below picture that the frame was hit on something at some point, causing it to be smashed in/bent a little, it definitely happened long before I got the car, no idea how it happened.






The below pictures detail the massive rust hole I discovered under the undercoat behind the passenger rear sway bar mount. I treated the whole area VERY heavily with rust treatment stuff as you can see, and I don't think it can rust anymore even if I left it like this, I intend to add a huge coating of rubberized undercoat as well, to protect it even more. Should I have this area welded or is it not worth it. It seems that the metal that rusted away is fairly thin to begin with. The side metal (far thicker and stronger) is all in tact and OK.






Ideas and help on this situation would be VERY appreciated.......
