New to rust belt

Having lived with salt for so many years, my family has tried a lot of rust inhibitors. Zeibart seems to just trap contaminants underneath the spray, causing more problems later. The electronic boxes did nothing. Krown caused us weird issues like gaskets swelling and dirt/grime/salt that couldn't be removed from the underbody where it had been sprayed. My grandfather swore by spraying used motor oil on everything after every oil change, that seemed to work okay but it was messy and not environmentally friendly. Even with Krown, I'd still spray it off as much as you can, whether that be an automatic undercarriage wash or a low pressure garden hose. And at the end of the winter season, IMO it's definitely worth taking some time to spray off those hard to reach areas like shock towers, the bottom side of the vehicle body and up and around the gas tank/spare tire/skid plates/etc. Our 2017 still looked great underneath when we parted ways with it for our 2023 Limiteds, but rust in these parts is inevitable given enough time. Enjoy the snow at least!

 

I use this in march to get the underside thoroughly cleaned. I’m ocd and even take off the wheels to clean the fenders and suspension with some simple green and pressure washer.
