Was wondering what your thought's are about rustproofing . I have a fx4 getting built and have read both pro's and con's on rustproofing. The dealer was even pushing an elect (cathodic protection device ) ya hook up to the battery to combat rust. I did see a truck with the rear wheel well plastic fender liners that looked slick!!! Interested in what new owner's are doing if anything with there new rides. From mi with salty winters Thanks all
