2020 GMC Yukon — surface rust underneath a winter daily — anyone dealt with this recently?

WrenchHunter858Community StarterJan 11, 20262020 GMC Yukon DenaliColumbus

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? I am in Columbus. If I figure it out I will update the thread. Mileage is about 96,000.

I'd pick the setup I'll actually live with in slush. In Columbus, dedicated winters on the 2020 GMC Yukon paid off more than I expected on ice, even on plowed roads. Then you'll know the next fork. This is from a 2020 GMC Yukon in Columbus. Run the total, not the monthly, before you commit. Happens in gear, not in park, for what that's worth.
