I have what appears to be a rare factory defect on my paint job. I say rare, because my previous daily Subaru car has zero rust on it still and no other Subie owners out there I know has this issue. The rust is in the driver's door jam and still easily fixable, right under the trim.
Pulling up the trim and it looks to be surface rust.
I have purchased the following items. for the removal, 80 grit sanding paper. All based on other's work and experience on similar tasks.
