2018 Kia Optima — surface rust underneath a winter daily

There is early surface rust on brackets, fasteners and seams underneath, but nothing structural. For a salt-belt car, what treatment slows it down without creating a hard coating that traps moisture?

One thing that mattered for me: in Queens, I care more about the thing I will notice every day than the spec-sheet extra.
