@ebinmaine nice pick up on that , literally , opportunity for a creeping lubrication soak down , highest available access point to any closed area , tailgate , doors , cab to body areas , days out will show you tracking , what's. effective , what needs improvement . inside upper tailgate access , is a lubricant line showing itself days out with related film . like a lighter oil first , for tracking , then open gear and cable spray follow up . creeping on the lighter oil . napa , macks , cable oil is a good buy . would personally go over that paint with penetrant / then mineral oil , will clean up to an always slick looking finish , get the wheel wells first , or go to home depot parking lot for rust reference ! remember ford frames , have punched in holes ? they hold onto moisture , insuring rot . try a paint spot , related seaming , you just saved that area , good luck with it , oily pete
