That is very cool, my kids got a kick out of that idea. They say that one of their best memories was riding from Tallahassee to Gainesville in
"Aluminum Overcast". They were volunteers while the B-17 was on display at the Tallahassee airport and the older son had his name drawn from a hat as one of the 6 volunteers selected to ride to their next stop. He gave his seat to his younger brother since he had already flown in a C-130 on a trip to Cape Canaveral and back. The bomber crewmembers were so touched they told him to come on out in case someone canceled, then found an empty jump seat for him.

I wouldn't do it in drab (I actually saw a brand-new Nissan car tonight at a dealership painted up like an old Army Jeep), I'd consider leaving it in natural aluminum. Maybe add some invasion stripes or a roundel and star too. Bonnie and I were joking about building her a lightweight teardrop out of metal and decorating it like your idea, and decorate my offroad camper like a Jeep. We probably won't, but it's a way cool idea!
