start on 65 dart

Who said there was no rust on California cars. Leaking antifreeze was the culprit.
Picture 1 you can see the damage.
Picture 2+3 keep cutting till the @#$& rust all gone.
Picture 4 start to weld
Picture 5 all done.
all that is left is to clean up the rest of the floor.

There was a few blow throughs with the mig welding, how should i deal with this?
