As for removing any 'chunks of non-Porsche metalwork' . . . I wouldn't be too-too determined about removing all the battle scars. Your car has had quite the life, and, IMO, it would be a shame to erase all of it
My car came with a funky little braze repair on her left front battery box . . .

At the time, it never occurred to me to keep that repair intact --- I, mean . . . who would ever see it, right? . . . and so it was duly excised, perfectly
