Body work

Anyone with any advise on how to go about reparing some minor body rot on my rocker panels and lower A pillar? I just bought a MIG welder and had planned to buy replacement parts from Victoria Briish.

Thanks

Not Sure,
I just got my 79 back from the shop and discovered they apparently reset the hood wrong and when the bonnet was shut, a small dent was made from the inside going out..(hood was hitting alternator guard)..they of course do not remember doing it...but now I am attempting to figure a way to fix that one myself...
