humm heres how id do it... not by the book but cheapo(Y)
get some filler, preferably body filler
clean up the affected areas
apply filler
roughtly sand it down to smoothish doesnt have to be perfect
then either use some rubber sealer or rust paint stuff
then underseal the entire car
then your done

hope it helps and i do car body work too

cut the rust out first, weld new plates in if you want the repair to last. Theres no point slapping body filler ontop of rust else youll be doing the same thing in 12months time. (Y)

i sprayed mine with 50/50 engine oil and shutz, with a shutz-gun (the whole floor and axle/suspension etc)
it looks dry in the pic, but underneath the skin of dust its still sticky, so it does,nt matter if its already rusty (as long as its not holed)
