There is a huge thread on this topic and many solutions to remedy the situation. I stripped my hatch completely took it to a Powder coating shop, matched the color and had them do it
(Tuxedo Black ) and clear coat. That was over three years ago and still looking great! I don't know why Ford doesn't do the aluminum panels that way. The only issue I had was when they stripped it with the sand blasting some of the areas that are unsupported on the back side, need to be more gentle with the pressure and there can be some dimpling. It is not obvious until you put the final gloss on. I also saw a site where they sell replacement hoods of steel , which won't have his problem, but so far they don't have the rear hatch.
