Your last pics says all cleaned up with the big gaping hole still in the panel. All cleaned up would tend to make people believe it was done....... Hope yours was fixed right instead of just covered up.
Here is another thread to take a look at from a member here that did the repair the right way and also took it a little bit further as to cover the whole underside to protect it from rusting.
