I've sealed aluminum with clear coat. I did, however, do a sort of artistic scuff on the aluminum prior to the spray however. I also put a dose of pearlescent gold in the clear so that it appears to be straight clear, but when you see it an an angle it flashes gold. I'd check with an automotive paint store about shooting it without any "tooth" on the aluminum. I'm not sure what Airstream does on their clear coats. Doug
