CATHODIC PROTECTION!
"20 minutes of research showed me that FORDS position is to deny ANY claims for paint....and they are winning every case because there is no "rust thru". Go ahead for those that can't take my word, go do your own research and tell me how many cars Ford is warrantee-ing for paint.....ZERO! So this might be a good path forward or at least the beginning of a good path forward."
Zero? Then I'm the first...The Ford dealership took my 14 Expedition with bubbling paint on both the Hood and Tailgate. Their 1st question "How many miles"?...Mine is at month 33 and 30K. It's fully covered under the original factory warranty...No ifs, ands, or buts about it. It should be ready this week.
