This is a metal question but putting it here since it feels off-topic.
What's the best way to deal with this kind of rusting on a 20-year-old car? I've read all sorts of different methods from rust converter to fluid film, but want to check with the brain-hive here.
I don't really care to restore perfectly. I'm just looking to slow down and delay the rusting so it looks somewhat "respectable" for the family until the car explodes. My partner is pointing out skeleton cars around us and worried our car will look like them...
The first picture showed the rusting contained within the hard edge because I had masked, sanded, and primed these spots a few years ago. But the rust seems to have come to worsen in these areas?
What's the best path with the least time-consuming and skill required? I'm leaning towards just hand brushing some fluid film into these areas
