Rusted boat trailer

hey guys
looking for some tips/advice regarding a boat trailer I just bought
The boat and trailer was a bargain, but the trailer is very rusted.
Has anyone got any ideas as to what I should do with the trailer.
Should I sand it back and paint it with some sort of galv paint or leave it and paint over the rust
Im new to having a boat so dunno what is the best thing to do?
or should I leave it as is??
anything ideas will be appreciated
cheers
