Minor Rust Treament?

[thepunisher]

I'm curious how other members of the forum would repair this. It's only a small portion of the rocker panel so it doesn't justify replacement of the whole piece. The photo isn't the best, this entire area was knee deep in body filler and the hole at the top is the worst of it. It does need repair but what? I can make several small patches of sheet metal? I don't have the tools to bend up a perfect replacement piece.
