oh and just to make a point, notice that the sort of specific "components" you began by writing have never appeared at all. which is why i didn't even recognize your original question as really being in the same subject, or at least not in the same spirit. i.e. to me, using differential forms is about manipulating d and F*, not writing out "a upper ij" and so on.
