Hi guys, definitely should have checked this before buying the car (love it otherwise) What’s the best way to go about sorting these? Or are they past repair?

Looks like someone has been jacking it up under the sill lip and caused it to rust. I guess it can be repaired.

I had a bit of this on mine also I just wire brushed it then sanded it sprayed a rust resistant under coat then painted the lower sill there with a black car underseal.
