Don't have that much experience with flyable model aircraft, but I do remember as a kid going to a sleep away summer camp where one of the camp staff was working on a plane. He was taking a while to do it and was talking about whether or not he'd install an engine or just use rubber bands to hold the propellers in place as a more or less static model. But the thing that us kids found hilarious was that he was painting it with "fuel proof dope".
