My hood is only starting under the inside front edge, hope it stays there. I see no signs on the rear hatch. With the 2015 F150 being all aluminum, hope Ford got it right.
My 2010 tail gate just started to blister near the chrome. How does the paint stick to the new F150 ? Why buy one ?
Disclosure : First, I used to work at Ford in Engineering. Nothing to do with paint or body.
Second, my daughter's 2012 Expedition has the same paint bubbling problem on the tailgate, so I am not a "happy camper" !
We need to understand that this not a PAINT problem. This a SURFACE PREPARATION problem. Contamination (dirt/oil/grease/moisture) is on the bar aluminum surface before the primer and pint are applied. If it is on the surface before the hem flange is folded, well, we know the result.
Other items are made out of aluminum and are painted and do not oxidize. Why ?
First, different aluminum alloy have better/worse oxidation/corrosion resistance properties. They also have
varying other properties.
Second, they have special cleaners and chemical coatings applied before the primer and paint. (Alodine, anodize, etc)
Third, is proper primer. Either zinc-chromate or a "self etching" primer.
As for the F150, they are using a special coating called
Alcoa 951 in a
patented process.
Last, because stamping and assembling aluminum body panels require special equipment, it is likely that the hood and tailgate of the Expedition were made by a supplier. I don't know who, but their manufacturing process is not the "best in class" ! If they haven't changed that by now, they are not likely going to.
Looks we will have to wait until the Expedition gets am "all aluminum" body, built by Ford like the F150. 2017MY ? 2018MY ?
