    Have a 2020 driven in all sorts of salty conditions. I'm noticing a good amount of rust buildup on the frame and certainly want to take action.

    Has anyone tried Cosmoline RP-342 ? Other worthy solutions you swear by to prevent the damn rust from killing my beloved Tundra?

    thanks!

    I’d recommend fluid film, wool wax, surface shield type product especially if existing rust is present. Spray it on once a year on all metal and it will be well protected.

    I prefer Wool Wax to Fluid Film because Fluid Film smells terrible.
    They have the same great results
