2020 Kia Stinger — surface rust underneath a winter daily

DailyCommuter815Community StarterSep 4, 20262020 Kia Stinger GT2Portland
2020 Kia Stinger GT2, about 71,500 miles. 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'd pick the setup I'll actually live with in slush. In Portland, dedicated winters on the 2020 Kia Stinger paid off more than I expected on ice, even on plowed roads. That's where I'd start. On “surface rust underneath a winter daily,” that was the fork that mattered for me. Keep sale price, fees, and rate as three different conversations. I'll poke at it this weekend.

Salt and cold mornings punish cheap shortcuts. Watch brake clearance and overall diameter if you downsize winter wheels on the 2020 Kia Stinger. I'd do that before spending real money. No need to make it theatrical. That's coming from doing this as an owner, not a shop. Video is ugly but it shows the hesitation.

I parked the 2020 Kia Stinger and wrote down what I already tested so I'm not repeating myself. Cold start is when I can actually reproduce it.

Salt and cold mornings punish cheap shortcuts. Watch brake clearance and overall diameter if you downsize winter wheels on the 2020 Kia Stinger. Then you'll know the next fork. This is from a 2020 Kia Stinger in Portland with 71,500 miles. Do that first. If that fails I'll eat the diagnostic fee.
