2017 Nissan Altima 2.5 SV — surface rust underneath — treat now or leave it?

I found surface rust starting on a few brackets and seams underneath. Nothing looks structurally bad yet. For a car that sees winter salt, what treatment actually slows it down without creating a mess later? I'm in Pennsylvania. Any data points from owners would help.

Salt and cold mornings punish cheap shortcuts. Watch brake clearance and overall diameter if you downsize winter wheels on the 2017 Nissan Altima. I'd do that before spending real money. On “surface rust underneath — treat now or,” that was the fork that mattered for me. The universe charges extra for guessing. Cold start is when I can actually reproduce it.
