Lars,
I have used several old aluminum signs in the past (Got a great deal on a bunch one time that were printed incorrectly)... I found the easiest way to get that coating off was running small propane or butane torch over it. It just peels/shrinks/melts away, at least mine did. Just don;t put too much heat to it, but mine did not require a lot of heat time at all. (mine were like the vinyl graphic wrap type material for vans etc... - may not have been exactly, but it was similar)
