If you try to "pound" the dent out from the interior,
be SURE to have an assistant outside to buck the plate
while you hit it from the interior. If not you will
likely knock a hole through the skin. Good
communication is a must so they will know where to
buck against you while you gently try to get the dent
out. however, there will still be defects that will
show, no matter how careful you are. You just cannot
get it totally blemish free, but you can get the worst
of it out.
Good luck
