how you repair steel panel and also make it look nice ?
...you don't. You replace it in whole. You can't use filler to mask small dents and paint over it, if you want it to look as before, you have to pretty much replace it.
A steel panel would we repairable with the same tools a curved panel is. You can pull out dents without filler - filler is for fiberglass.
