I'd be confident using it too. If it didn't break while bending it, I doubt it will break after all the heat is put to it. I'm talking about the cosmetics mostly, getting the chin tuck on the area that is gaping and needing the extra filler. You can bash sheet metal into almost any shape, the stock for those kinds of lugs started out flat. I was trying to find some info on forming investment castings. I wonder if the tucking could be done during the heating of the lug during installation. That kind of thing isn't too unusual, but I have no idea what ICs can take.
