I’m taking my family and my 200 on a road trip soon to some snowy locales, and I’m a bit concerned about protecting my truck from corrosion. As a southern California guy I’ve never really looked into it before, and while I know stuff like fluid film exists, I really don’t want to coat the entire underside in a layer of black gunk that’ll make working on it a slimy goopy mess in the future. The truck is really clean underneath and I’d like to keep it that way. Is there an easy temporary corrosion protector I can spray on? Has anyone used the PB Blaster surface shield or WD40 corrosion protector stuff?
