my paint is really suffering, mostly behind the right rear tire, from rocks and mud i kick up offroad. small dings from it also. what have you guys used to keep the lower end of your bodies from getting beat to hell? bedliner is something i've considered, but professionally done liners are too expensive and the diy versions are much less durable, from what i've seen. i'd like to avoid metal, since the beast weighs enough as it is. anyone tried magnetic vinyl sheets? melting plexiglass to shape, maybe? i know my offroad toy can't stay as pretty as my daily driver, but i'd like to at least try to keep it decent.
