My hood has been welded together. I am surprised that your search didn't find anything about that because I did post here about my experience.
I told Fran that I was going to weld the hood since the parting strip was in bad shape. One day I came home from work to find out that she had "helped out" by going ahead and welding it up for me. Trouble is she just grabbed the MIG and did one big long bead. The hood was warped. The good advice from the guys here was to do the weld in stitches to avoid warping but she hadn't read that. Take your time and let it cool. Go back and fill in the gaps until you have a continuous bead - should take about 5 passes, letting it cool between passes.
Anyway, my hood was warped and people here told me that the hood was ruined - go get a new one. I was not willing to accept defeat. I cut out the worst sections, flanged the edges and welded in patches. I also added reinforcing strips to stop the hood from oil canning. The gap was not filled with Bondo; I used long strand fiberglass filler. A skim layer of Bondo was added just to make it smooth. The underside of the hood isn't pretty with the patches and reinforcing strips, but that can be hidden by insulation
Personally, I like the look of the smooth hood.
