its fine to apply bodyfiller to bare metal, rust under the bodyfiller only happens if water is absorbed into the filler. if you are going to work the filler and then prime it ,corrosion wont be an issue. the issue with primer is that the UV rays from the sun break down the primer and will allow water to be absorbed. when you prime it , its best to base/ clear it soon.
