I use both on my /13 Expee : Carpro IronX makes the 'claybar' task more doable by far . Each spring I do the entire white exterior to remove the iron-filings road rust ."twas the same on my white Explorer. Ford just can't come up with good paint !!My /13 Expee has major rear issues with paint blisters around the chrome . Dealer here in BC asked Ford to "re-call' repair it but the response was NO !! { we Expee Owners need a class action plus Media support effort to get Ford embarrassed by paint problems on Expedition rear tail gates . }} Ford is well aware of the cause according to THE Dealership Owners here in BC 's Shuswap // North Okanagan . fothco
