I ripped part of the corner capping away while offroading, I just drilled the rivets out, straightened out the bent bits the best I could and then rivetted it back on, I used very slightly bigger diameter rivets and had to make a few new holes where the panel no longer aligned due to the panel stretching a bit with the dent....if its a cosmetic job it should be easier I would think.......I'd get some galvanised ones if I was going to be keeping it
